What type of energy transfer is responsible for making you feel cold when you are swimming in cool water? Explain your answer

6 0

The energy they are reffering to is heat . When you swim in cold water the heat of your body is transffered to the water becasue i guess it s because it wants to reach and enqilibrium within the systems.Nature in general doesn t like gradients.And also in water we loose more heat compared to air of the same temperature i guess this happens because water compared to air is a liquid it has (greater density, it s directly in contact with our body)

Answer:

3.41 x10⁶ torr

Explanation:

To solve this problem we need to remember the equivalency:

1 torr = 133.322 Pa

Then we can proceed to convert 4.55×10⁸ Pa into torr. To do that we just need to multiply that value by a fraction number, putting the unit that we want to convert from in the denominator, and the value we want to convert to in the numerator:

4.55x10⁸ Pa * $\frac{1torr}{133.322Pa} =$ 3.41 x10⁶ torr
