Explanation:
when water in a metal pot is heated over a campfire. Primarily, by means of convection energy transfer is thermal energy moved from the fire to the bottom of the pot
<h3 /><h3>What is thermal energy?</h3>
It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.
Thermal energy can flow by different means such as conduction, convection, and radiation.
As given in the problem when water in a metal pot is heated over a campfire. The energy we receive around the campfire is mostly due to the effect of the radiation of the heat but the Primary means of energy transfer is thermal energy moved from the fire to the bottom of the pot because of the convection.
Thus, when water is heated in a metal pot over a campfire. Thermal energy is primarily transferred from the fire to the bottom of the pot through convection.

Answer:
<h2>0.094 kg</h2>
Explanation:
Latent heat of vaporization of
at 37°C is
.
When the sweat on our body evaporates, it absorbs energy from our body to overcome it's Latent heat of vaporisation. Thus our body cools down when sweat evaporates.
So, Energy absorbed by sweat to evaporate = Energy lost by body
Specific heat capacity of human body =
. Jogger weights 60.4 kg. Body temperature decreases by 
Energy absorbed from body = 

∴ 0.094 kg of sweat has evaporated from the body.
The sun strikes the most at the equator. The sun strikes lowest at the poles.
Refraction is the change in direction of waves that occurs when waves travel from one medium to another. It is always accompanied by a wavelength and speed of change. Diffraction is the bending of waves around obstacles and openings.
