Question

The specific heat of water is 4.184 J/g˚C How much heat energy is absorbed when 88.0 g of water is heated from 5.8 C to 35 C? (Hint: it is just like example#1). Don't forget units and round your answer to the second decimal place. *

Answer 1

Answer:

The heat absorbed is hence 10.751.21 J

Explanation:

The heat absorbed when 88g of water is heated from 5.8°C to 35 °C is;

Heat = m c ΔT

m = 88.0 g

c = specific heat of water = 4.184 J/g°C

ΔT = ( change in temperature) = ( 35 - 5.8)°C = 29.2°C

Equating these values into the formula, we obtain;

Heat = 88* 4.184 * 29.2

Heat = 10 751.2064 J

Heat = 10 751.21 J (2 d.p)

The heat absorbed is hence 10.751.21 J
