A sample of helium gas has a volume of 1.25 L and a temperature of 22 °C, under a constant pressure. What is the new volume if the temperature is increased to 45 °C?

Answers

Answer:

the new volume is 1.35L

Explanation:

The computation of the new volume in the case when the temperature rises to 45 degrees is shown below:

GIven that

Volume = 1.25L

And, the temperature is 22 degrees celsius

So, [tex]T_1[/tex] = (275 + 22)k

= 297 k

Now

[tex]T_2[/tex] = (275 + 45)k

= 320 k

Now as it is a constant pressure

So, the new volume is

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2} \\\\V_2 = \frac{V_1}{T_1}\times T_2 \\\\= \frac{1.25}{297}\times 320[/tex]

= 1.35L

hence, the new volume is 1.35L

What does the force of gravity between two objects depend on?
A. The masses of the two objects and the distance between them
B. Only the mass of the smaller object and its distance from the
larger object
C. Only the masses of the two objects
D. The mass of the smaller object and the speed at which it's moving

Answers

Answer:

A

Explanation:

Answer:

Explanation:

The formula for the force of gravity is

F=G * m1 * m2 / r^2

G is a constant. It does not change with the use of the formula.  There are 2 masses, so the force depends on the masses.

The right hand side is divided by r^2. that's a distance. So that's the other quantity influencing the Force.

B: incorrect. Both objects have masses. That determines the force between them.

C: incorrect. It's also the distance between them.

D: incorrect. The formula contains nothing to indicate that velocity is important.

The answer is A

ANALYZE A ball of clay is manipulated into different shapes in each of the images
below. Does the amount of mass and matter in each of the images below change as
the size and shape of the clay ball is changed? Explain your reasoning.

Answers

Answer:

The amount of mass and matter in all the transformations of the clay ball will remain the same or constant

Explanation:

From the  law of conservation of mass we have, for an enclosed system to and from which there is no transfer of matter or energy, mass cannot be created nor destroyed, and remains constant at the given value, but the matter which make up the mass can be changed into different forms

Therefore, the clay ball can be transformed into different shapes and will still posses the same initial mass before the transformation, provided there are no transfer of matter or energy from the clay ball system.
