If 155 J of heat energy is applied to a block of silver weighing 27.9 g, by how many degrees will the temperature of the silver increase?

The temperature increase = 23.15 °C.

Explanation:

Given data:

Mass of silver = 27.9 g

Heat added = 155 j

How many degree temperature increase = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity of silver is = 0.240 j/g.°C

Now we will put the values in formula.

155 j = 27.9 g × 0.240 j/g.°C  × ΔT

155 j = 6.696  j/°C  × ΔT

ΔT  = 155 j /6.696  j/°C

ΔT  = 23.15 °C
