An 800-W heater raises the temperature of 4 kg of soup by 40 °C in 13 minutes.
(a)
How much energy is transferred to the soup if there is no energy loss to the surroundings?

Q=0.16*c kJ

Explanation:

Heat transfer and energy changes is related by the equation

Q=mcΔT

where

Q=heat transfer

m=mass of substance

c=specific heat of the material

ΔT= change in temperature

Given

m= 4 kg

c=c

ΔT=40° C

Q=4*c*40

Q=160c

Q=160/1000*c kJ

Q=0.16*c kJ

explanation:

specific heat is the amount of heat required to raise the temperature of a unit mass of a substance.

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.
