Specific Heat Problems

Front

What is specific heat?

Back

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

Front

What is the formula to calculate heat energy (Q)?

Back

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

Front

How does heat flow between objects?

Back

Heat flows from warmer objects to cooler objects until thermal equilibrium is reached.

Front

What is the specific heat of water?

Back

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

Front

If 2400g of water is heated from 25°C to 100°C, how much heat energy is required?

Back

752,400 J.

Front

What is the specific heat of aluminum?

Back

The specific heat of aluminum is 0.21 cal/g°C.

Front

How do you calculate the change in temperature (ΔT)?

Back

ΔT = final temperature - initial temperature.

Front

What happens to heat energy when water cools down?

Back

Heat energy is released to the surroundings.

Front

If a metal absorbs 350.0 J of energy and its temperature changes from 25.0 °C to 35.0 °C, how do you find its specific heat?

Back

Use the formula c = Q / (m * ΔT), where Q is the heat absorbed, m is the mass, and ΔT is the change in temperature.

Front

What is the heat energy released when 10g of aluminum cools from 100°C to 50°C?

Back

105 J.
