A35 gram piece of silver is droped into a container of water. as it cools the silver gives off 180 calories of heat. what is the silvers temperature change?

ΔT = -92°C

Explanation:

given,

mass of silver = 35 g  

heat = 180 cal

temperature change = ?

The specific heat capacity of silver is 0.056 cal/g C

using heat formula for calculation of temperature.

Q = m Cp ΔT

180 = 35 x 0.056 x ΔT

ΔT = -92°C

negative sign is used because silver is cooled and temperature change is from high temperature to low.
