1

An exothermic reaction is one in which heat energy is

given out

2

An endothermic reaction is one in which heat energy is

taken in.

3

In an endothermic reaction the products have more energy than the reactants because

the energy has been absorbed

4

Combustion is an

exothermic reaction

5

Energy released during combustion can be calculated using

Eh = cmΔT

6

In the Eh = cmΔT equation, c is always

4.18 kj

7

In the Eh = cmΔT equation, m is

The mass of the water in kg (100cm3 = 0.1kg)

8

In the Eh = cmΔT equation, t is

the change in temperature
