11D Specific Heat Calculations

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the formula to calculate heat (Q)?

Back

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

Front

What does a high specific heat indicate about a substance?

Back

A high specific heat means it requires more energy to change its temperature.

Front

What is the specific heat of water?

Back

The specific heat of water is 4.184 J/g°C.

Front

How much heat is released when 10.0 g of aluminum cools from 100.0°C to 50.0°C?

Back

451 J.

Front

What is the specific heat of aluminum?

Back

The specific heat of aluminum is 0.9025 J/g°C.

Front

If 20.0 g of water cools from 25.0°C to 20.0°C, how much heat is lost?

Back

418 Joules.

Front

What is the specific heat of copper?

Back

The specific heat of copper is 0.39 J/g°C.

Front

How do you calculate the temperature change (Δt) when heat is added?

Back

Δt = Q / (m * c), where Q is heat added, m is mass, and c is specific heat.

Front

What is the symbol for specific heat?

Back

The symbol for specific heat is c.
