Which statement best describes what is happening at

12345 [234]

Answer:

Water is absorbing heat.

Explanation:

Water is able to absorb heat

-<u> without increasing much in temperature</u> - better than many substances.

This is because for water to increase in temperature, water molecules must be made to move faster within the water; this requires breaking hydrogen bonds, and the breaking of hydrogen bonds absorbs heat.

A 0.180 kg ball falls 2.5 m. How much work does the force of gravity do on the ball?

kifflom [539]

The amount of work done by the force of gravity on the ball is 4.41 Joules.

<u>Given the following data:</u>

Mass of ball = 0.180 kg.

Displacement = 2.5 meters.

<u>Scientific data:</u>

Acceleration due to gravity = 9.8 $m/s^2$ .

To calculate the amount of work done by the force of gravity on the ball:

<h3>How to calculate work done.</h3>

In Science, work done is calculated by multiplying force and the height or displacement experienced by an object.

Mathematically, work done is given by the formula:

$Work\;done = force \times displacement = mgh$

Substituting the given parameters into the formula, we have;

$Work\;done = 0.180 \times 9.8 \times 2.5$

Work done = 4.41 Joules.
