Heat and Specific Heat

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

How do you calculate the amount of heat absorbed or released?

Back

Q = m * c * ΔT, where Q is the heat absorbed/released, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is 4.18 J/g°C.

Front

What does a high specific heat capacity indicate about a substance?

Back

A high specific heat capacity indicates that a substance can absorb a lot of heat without a significant change in temperature.

Front

What is thermal conductivity?

Back

Thermal conductivity is the property of a material to conduct heat, determining how well a material can transfer heat from one point to another.

Front

What does a high thermal conductivity indicate about a material?

Back

It indicates that the material can efficiently conduct heat.

Front

If 500J of heat is added to 200g of aluminum at an initial temperature of 25°C, what is the final temperature?

Back

28°C

Front

What is the formula for calculating heat transfer?

Back

Q = m * c * ΔT.
