Complete the passage to explain how thermometers work.
Temperature is read by measuring the liquid in the thermometer using the scale on the thermometer. When the temperature rises, the liquid in the thermometer
. When the temperature drops, the liquid in the thermometer
Answer:
Temperature is read by measuring the liquid in the thermometer using the scale on the thermometer. When the temperature rises, the liquid in the thermometer rises. When the temperature drops, the liquid in the thermometer drops.
Explanation:
got it right on edge
When the temperature is increase so the liquid in the temperature should be rised.
When there is a fall in the temperature the liquid in the thermometer should be fallen.
Working of thermometers:
The temperature should be read via calculating the liquid in the theromemeter by applying the scale occur in the thermometer. At the time when the temperature is increase so the liquid in the temperature should be rised. While on the other hand, When there is a fall in the temperature the liquid in the thermometer should be fallen. This means it shows the direct relationship between them

Find the density of a substance with a mass of 5.0 kg and a volume of 43 m3.
An object has a density of 10.00 g/mL. If the object has a volume of
25.00 ml, what is the mass?
Answer:
The answer is
250 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume of object = 25 mL
Density = 10 g/mL
The mass of the object is
mass = 25 × 10
We have the final answer as
250 gHope this helps you

Explanation:
6.72 x 10^12 in standard form
Answer:
6.72*10¹²= 6,720,000,000,000 in standard form.
Explanation:
Scientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a * 10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10. n is an integer called an exponent. Represents the number of times the comma is shifted. If the exponent is positive, move the decimal point to the right. And if the exponent is negative, move the decimal point to the left.In this case 12 is a positive number, so the decimal point is shifted to the right 12 places.
So, 6.72*10¹²= 6,720,000,000,000 in standard form.

a:Bonds are used to make new substances.
b:Building and breaking bonds are part of the energy cycle.
c:Bonds create new elements.
d:Chemical bonds sustain life.
Answer:
the answer would be B :)
The correct answer is; Bonds create new elements
Chemical bonds are formed when two or more atoms are joined together to form a compound.
Chemical compounds are more stable than the respective elements from which they are formed.
Chemical bonds do not create new elements.

9.56 x 10^5 cg is how many grams?
Answer:
9.56×10¯⁷ g.
Explanation:
Mass in cg = 9.56×10¯⁵ cg
Mass in g =.?
Thus, we can convert 9.56×10¯⁵ cg to grams (g) as illustrated below:
Recall:
1 cg = 0.01 g
Therefore,
9.56×10¯⁵ cg = 9.56×10¯⁵ cg × 0.01 g / 1 cg
9.56×10¯⁵ cg = 9.56×10¯⁷ g
Therefore, 9.56×10¯⁵ cg is equivalent to 9.56×10¯⁷ g.

What is kinetic energy?Kinetic energy is a form of energy it possess when any object or person is in motion . It can be defined as the work needed to be done to produce a motion in a object from rest position.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Mathematically,
Kinetic energy =1/2mv^2
Where
m = mass of object.
v = velocity of object
Kinetic energy is vector quantity it means that it have both i.e magnitude and vector. . It can be defined as the work needed to be done to produce a motion in a object from rest position.
S.I unit of Kinetic energy is Joule.

Which of the following mixtures could be separated using distillation? Select all that
apply.
O A solution of rubbing alcohol and water.
A solution of salt and water.
An alloy of copper and gold.
O A solution of sugar and water.
The solutions which can be separated using distillation are that of alcohol, salt and sugar with water.
What is distillation ?It is defined as a process by which components are separated from a mixture which is liquid by selective boiling and condensation. Dry distillation is a process of heating solids to produce products in gaseous state.
Distillation results in complete separation of components or may be sometimes partial.Due to partial separation,concentration of selected components increases in the mixture. It exploits differences in relative volatility of components of a mixture.
It has many applications like distillation of fermented products which produces distilled beverages , in desalination and in petroleum and oil industry.
It is mainly conversion of liquid into vapor state ,which is subsequently converted back to liquid . It is used to separate volatile liquid from solids and also volatile liquids and non-volatile liquid .

In one second an ant dragged an object 1 mm. What was its speed in cm/min?
Answer:
The speed of the ant is 6 [tex]\frac{cm}{min}[/tex]
Explanation:
Speed is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, velocity relates change in position (or displacement) with time by:
[tex]speed=\frac{distance}{time}[/tex]
In this case:
speed= ?distance= 1 mmtime= 1 secondReplacing:
[tex]speed=\frac{1 mm}{1 second}[/tex]
Being 1 mm equivalent to 0.1 cm and 1 seconds equal to 0.01667 minutes then:
[tex]speed=\frac{1 mm}{1 second}=\frac{0.1 cm}{0.01667 min}[/tex]
speed = 6 [tex]\frac{cm}{min}[/tex]
The speed of the ant is 6 [tex]\frac{cm}{min}[/tex]

An antimony, Sb,atom contains 51 protons inside the nucleus and 51 electrons outside the nucleu
A mercury, Hg, atom contains 80 electrons and 80 protons inside the nucleus.
Answer:
Antimony, Sb, an atom contains 51 protons inside the nucleus and 51 electrons outside the nucleus.
Explanation:
Option “C” is correct because protons exist inside the nucleus and electrons exist outside the nucleus. Moreover, Sb has the number of protons 51 that is found in the nucleus and it has 51 electrons that exist outside the nucleus. However, the nucleus contains protons and neutrons while electrons exist outside of the nucleus. All the given options do not follow such condition therefore, all the statements are incorrect accept option 3rd.
