Question 4 (9 points) How many joules of energy are required to hear 200.0 grams of water from 25.0°C to 125.0°C?

62.7KJ

Explanation:

How many joules are required to heat 200 grams of water from 25˚C to 125˚C? 524.8 kJ

Start with Specific Heat because the water is not going through a phase change.

m= 200 g

Cp= 4.18 J/g˚C must be given

∆T= 100˚C - 25˚C = 75˚C

q =mCp∆T

q = (200g)(4.18 J/g˚C)(75˚C)

q = 62700 J = 62.7 kJ

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
