Answer 1

Answer #1

Specific heat of water is 4.184 J/goC

As we know , the specific heat of water is the amount of heat required to increase the temperature of 1 gram of the substance to 1 oC.

So to increase the temperature of 32.5gm of substance to (35.22 - 24.73) = 10.49 oC , putting the formula Q= MC∆T

where M is the mass of the substance.

C is the specific heat of water.

∆T is the temperature difference.

Heat required = 32.5 × 4.184 × 10.49 = 1426.43J .

So 1426.43J of energy is required to increase the mass of M=32.5gm of substance of temperature 35.22 oC to 24.73 oC .
