How do the units that are used to measure heat differ from the units that are used to measure temperature?

Answers

Answer: The fundamental difference between heat and temperature is that Heat is the form of energy that transfers from a hot state to a cold state. The unit of Heat is Joule. However, the temperature is the measure of the hotness and coldness of an object. The SI unit of Temperature is Kelvin.

Heat is measured in Joules. Temperature is not energy. It relates to the average kinetic energy of microscopic motions of a single particle in the system per degree of freedom. It is measured in Kelvin K ,Celsius C or Fahrenheit F.

What type of energy transfer is taking place as the coils in a toaster heat?

Answers

Answer: A toaster uses infrared radiation to heat a piece of bread (see How Thermoses Work for information on infrared radiation). When you put your bread in and see the coils glow red, the coils are producing infrared radiation.

Because

When operating in this mode, heat is transferred between two entities that are really in contact.

Mass is 4 grams and density is 2g/mL. what is the density

equation=
answer=

Answers

I think your answer is 168.56
Density= mass over volume
2= 4/v
V= 2

Which has a higher density? Helium or air?

Answers

Answer:

Air

Explanation:

In the case of your helium balloon, it most likely floated away before you could catch it because helium is much lighter (or less dense) than the air in our environment.

Air has a higher density.

hope this helps! :)
