Which sentence correctly explains the process and conditions needed for hail to form? (2 points) Group of answer choices

The temperature of the air and the temperature of the cloud must be below zero.

Liquid water requires temperatures above 0 °C in order to remain in a liquid state.

A form of precipitation requires melting and refreezing as they fall towards the ground.

Ice chunks move around inside a cloud, bouncing into water droplets and growing as they fall.

  A form of precipitation requires melting and refreezing as they fall towards the ground.

Explanation: The hail begins as rain and freezes as it falls down to the surface.

1) 385 J

2) 450 J

Explanation:

1)

The amount of energy that must be absorbed by a certain substance in order to increase its temperature by is given by the equation:

where

m is the mass of the substance

C is its specific heat capacity

is the increase in temperature of the substance

For the block of copper in this problem, we have:

m = 10 g is the mass

is the specific heat capacity of copper

is the change in temperature

So, the energy absorbed by the block of copper is

2)

Similarly for the block of iron, the energy absorbed by the iron is given by

where

m is the mass of the block of iron

C is its specific heat capacity of iron

is the increase in temperature of the block

Here we have:

m = 10 g is the mass of the block

is the specific heat capacity of iron

is the change in temperature

So, the energy absorbed by the block of iron is
