What is specific heat capacity?

Back

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

Front

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

Back

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

Front

How do you calculate the mass of a substance using heat energy, specific heat, and temperature change?

Back

Rearranging the formula Q = m * c * Δt gives m = Q / (c * Δt).

Front

What is the specific heat of water?

Back

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

Front

If 150 J of heat is added to 50 g of aluminum with a specific heat of 0.90 J/g°C, what is the temperature change?

Back

Δt = Q / (m * c) = 150 J / (50 g * 0.90 J/g°C) = 3.33 °C.

Front

What is the specific heat of aluminum?

Back

The specific heat of aluminum is 0.897 J/g°C.

Front

How do you find the final temperature of a substance after adding heat?

Back

Final temperature = Initial temperature + (Q / (m * c)).

Front

What is the unit of specific heat capacity?

Back

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

Front

If a 20 g piece of aluminum is heated from 30°C to 80°C, how much heat is absorbed?

Back

Q = m * c * Δt = 20 g * 0.897 J/g°C * (80°C - 30°C) = 1076.4 J.

Front

What is the relationship between heat energy and temperature change?

Back

Heat energy is directly proportional to the temperature change for a given mass and specific heat.
