Question

I n an exothermic reaction the temperature of a 155 water bath is raised 3.2 degrees celcius how many joules does the water absorb Cp for water equals 4.18 jouls / grams degrees celcius

Answer 1

2073.28 Joules

Step-by-step explanation:

Mass, M = 155g

Change in temperature, ΔT = 3.2 degrees celcius

Specific heat capacity, C = 4.18 jouls / grams degrees celcius

Heat, H = ?

The properties are related by the following equation;

H = M C ΔT

H = 155 * 4.18 * 3.2

H = 2073.28 Joules
