FLASHCARD QUESTION

Front

What is the formula for calculating heat transfer in thermochemical calculations?

Back

q = mCΔT, where q is the heat absorbed or released, m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

FLASHCARD QUESTION

Front

In thermodynamics, what does the term 'specific heat capacity' mean?

Back

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

3.

FLASHCARD QUESTION

Front

What direction does heat flow between two substances at different temperatures?

Back

Heat flows from the substance with a higher temperature to the substance with a lower temperature.

4.

FLASHCARD QUESTION

Front

If two substances of equal mass absorb the same amount of heat but have different temperature changes, what can be inferred about their specific heat capacities?

Back

The substance that experiences a smaller temperature change has a higher specific heat capacity.

5.

FLASHCARD QUESTION

Front

How do you calculate the specific heat capacity of a substance?

Back

Specific heat capacity (C) can be calculated using the formula C = q / (mΔT), where q is the heat absorbed, m is the mass, and ΔT is the change in temperature.

FLASHCARD QUESTION

Front

What is the specific heat capacity of water?

Back

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

7.

FLASHCARD QUESTION

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases as it absorbs heat, assuming no phase change occurs.
