The specific heat of silver is 0.06 Cal/ G°C. 50 g of silver will require calories to raise the temperature 1°C
sergejj [24]

Answer: 3 Calories of heat will be required by silver to raise the temperature to 1°C.

Explanation: Specific heat is defined as the heat required to raise the temperature by 1°C for 1 gram of substance.

Mathematically,

q=mc\Delta T

where,

q = heat required = ? Cal

m = Mass of the substance = 50 g

c = Specific heat of the substance = 0.06Cal/g^oC

\Delta T = Change in the temperature = 1°C

Putting values in above equation, we get:

q=50g\times 0.06Cal/g^oC\times 1^oC\\q=3Cal
