Thermochemistry Intro

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

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°C.

Front

How do you calculate heat transfer?

Back

Heat transfer (q) can be calculated using the formula: q = mass (m) × specific heat (c) × change in temperature (ΔT).

Front

What is the specific heat of water?

Back

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

Front

What happens to heat during an exothermic reaction?

Back

During an exothermic reaction, heat is released into the surroundings.

Front

What happens to heat during an endothermic reaction?

Back

During an endothermic reaction, heat is absorbed from the surroundings.

Front

What is the direction of heat flow?

Back

Heat flows from warmer objects to cooler objects.

Front

What is the relationship between temperature and exothermic reactions?

Back

In exothermic reactions, the temperature of the system increases as heat is released.

Front

What is the relationship between temperature and endothermic reactions?

Back

In endothermic reactions, the temperature of the system decreases as heat is absorbed.
