The specific heat capacity of a substance is the amount of energy associated with doing which of the following to 1kg of the substance?

Raising its temperature by

Explanation:

The specific heat capacity of a substance is defined as the amount of energy needed to raise the temperature of 1 kg of a substance by .

The specific heat capacity of a substance essentially tells us how much energy is needed to heat the substance: the larger it is, the more energy is needed. The amount of energy needed to increase the temperature of a substance is given by

where

m is the mass of the substance

Cs is the specific heat capacity

is the temperature variation of the substance

answer: what are you talking about?

explanation:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
