Jessica places 100. g of water at 20.0℃ in an insulated cup. The specific heat capacity of water is 4.18 J/(g℃). What is the final temperature of the water if 5000. J of energy is added to the water in the insulated cup?

31.96°C

Explanation:

Given that,

Mass of water, m = 100 g

Initial temperature,

The specific heat capacity of water is 4.18 J/(g℃)

We need to find the final temperature of the water if 5000. J of energy is added to the water in the insulated cup.

The heat added to the water is given by :

So, the final temperature is 31.96°C.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
