Answer:
106.24 kJ.
Explanation:
Given that,
Mass of sample of sand, m = 8 kg
Specific heat of sand, c = 664 J/kg-°C
The temperature changes from 20° C to 40° C. We need to find the change in thermal energy. It is given by :
So, the change in thermal energy is 106.24 kJ.
Q. Which motion causes the Coriolis effect on Earth?
A. (3) rotation of Earth on its axis
Q. When water vapor condenses, how much heat energy will be released into the atmosphere?
A. 2260 joules/gram
All of the above. they would all decrease due to a lack of energy from using it in the beginning.
