98 \times mass \text { joule } is the potential energy of the ball as it is half way through the fall, 20 meters high

<u>Explanation:</u>

Given data:

Height of the fall = 20 m

Given that the body is half-way through the fall, it is at above the ground 10 m

          \frac{1}{2} \times 20=10 \mathrm{m}

We need to find its potential energy (P.E)

Energy due to the body’s position is referred as potential energy. It means the energy when body is at rest. It can be expressed as below,

         \text { Potential energy }=m \times g \times h

Where

m – The body’s mass

g - Acceleration due to gravity  \left(9.8 m / s^{2}\right)

h - Height of the body

By substituting the given values, we get

           Potential energy =m \times 9.8 \times 10=98 \times m\ joule

Since the mass is not provided, just kept it.

Which is a property of an ideal gas?
AlekseyPX
HEY THERE!

THE ANSWER IS: the properties of an ideal gas are: An ideal gas consists of a large number of identical molecules. The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas. The molecules obey Newton's laws of motion, and they move in random motion.

Using the following equation for the combustion of octane calculate the heat associated with the formation of 100.0 g of carbon
natali 33 [55]

Answer:

The right solution is "-602.69 KJ heat".

Explanation:

According to the question,

The 100.0 g of carbon dioxide:

= \frac{100.0 \ g}{114.33\  g/mole}

= 0.8747 \ moles

We know that 16 moles of CO_2 formation associates with -11018 kJ of heat, then

0.8747 moles CO_2 formation associates with,

= -\frac{0.8747}{16}\times 11018 \ KJ \ of \ heat

= -0.0547\times 11018

= -602.69 \ KJ \ heat
