Specific Heat PRACTICE

Front

What is Specific Heat?

Back

The amount of thermal energy required to increase the temperature of 1 kg of a material by 1°C.

Front

What unit do you use to measure Thermal Energy?

Back

J (Joules)

Front

How much heat (Q) is released when a 10 g piece of aluminum cools from 100° to 50°?

Back

105 J

Front

What does a high specific heat indicate about a substance?

Back

It requires more energy to change temperature.

Front

Which substance will heat up most quickly when placed in a warmer room: Iron, Aluminum, Lead, or Zinc?

Back

Lead

Front

What is the specific heat of aluminum?

Back

0.21 cal/g°C.

Front

If a substance has a low specific heat, what does that imply about its temperature change?

Back

It heats up quickly with energy added.

Front

What is the formula to calculate heat (Q) in relation to specific heat?

Back

Q = mcΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is the specific heat of water?

Back

4.18 J/g°C.

Front

Why is water's specific heat important for climate?

Back

It helps regulate temperature by absorbing and releasing heat slowly.
