Please someone answer, I will mark them who answers as brainliest, How much energy is needed to heat 100 kg of paraffin from 10 degree Celsius to 30 degree Celsius. The specific heat capacity of paraffin is. 2200 unit.

40,000J

Explanation:

The heat energy required to raise the temperature of unit mass of substance through unit degree is called specific heat of substance . As given 2000J energy is needed to heat 1 kg of paraffin through 1

o

C, therefore specific heat of paraffin will be 2000J/kg−

o

C.

Now, heat energy required to raise the temperature of mass m of substance (specific heat c) through Δt is given by ,

Q=mcΔt,

Given: m=10kg,Δt=2

o

C,c=2000J/kg−

o

C

Q=10×2000×2=40,000J

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
