What happens in terms of heat transfer when you hold a snowball in your hand?

Answer 1

From your hand to the ice cube as your hand is at a higher temperature than an ice cube and thermal energy flows from a higher temperature to a lower temperature.

Answer 2

Acutually, it's not the "cold" you feel, but the lack of heat. Heat naturally travels from warm to cold. It's warmer in your hand than in the snowball, so heat naturally travels to the snowball. Your hand becomes colder because it is losing heat, which is why it feels cold.

Answer 3

That depends on what happens to its speed. The formula for kinetic energy is:

KE = m(v)^2, in which m is mass in kg and vis speed in m/s.

If either the mass or the speed increases, the kinetic energy will increase. So if the mass of the rolling snowball increases, but the speed remains constant, its kinetic energy will increase.

However, in reality, due to friction between the snowball and the ground, the speed will decrease until the snowball stops. So the kinetic energy under natural conditions would decrease, even though the mass increases.

Answer 4

If you keep pushing it, then it has whatever amount of kinetic energy you give it by pushing.

If you give it a strong push and let it go, and if it's rolling across level ground, then it can never
have more kinetic energy than it had when it left your hand. If it gains mass in the form of
sticky snow, then its speed must decrease.

Answer 5

When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.

Answer 6

the snow ball will melt cause the heat produced in your body will raise the temperature of the snowball

Answer 7

It melt

Answer 8

Conduction
