Back

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

2.

FLASHCARD QUESTION

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.

FLASHCARD QUESTION

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).

What is the specific heat of water?

Back

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

5.

FLASHCARD QUESTION

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.
