Do you agree or disagree with the scientists who downgraded Pluto?

Well scientificly yes, I agree. This mainly is due to the fact that pluto does not meet the qualifications of a planet and behaves more similarly to the patterns of a dwarf planet. For example, pluto moves in an oblong cycle around the sun and not a "perfect circle". It almost seems that pluto is thrown off its path.

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.
