The molecules of a gas are in constant random motion. This means that they have energy in what type of energy store?

Physics
1 answer:
serious [3.7K]3 years ago
3 0

Answer:

Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

A 160-N child sits on a light swing and is pulled back and held with a horizontal force of 100 N. The magnitude of the tension f
guajiro [1.7K]

Answer:

T = 190 N

Explanation:

When child is sitting on the swing then the weight of the child is vertically downwards

So it is

F_g = 160 N

now a force of 100 N is acting on the swing in horizontal direction

so it is given as

F_x = 100 N

now the net force is resultant force due to gravity and horizontal force

so it is given as

T = \sqrt{F_x^2 + F_g^2}

T = \sqrt{100^2 + 160^2}

T = 190 N

What must be attached to each carburetor on a gasoline inboard engine?
alekssr [168]
To each carburetor on a gasoline inboard engine a backfire flame arrestor must be attached.This arrestor will <span>prevent flames from the backfire causing a fire on board.  Several things are important in order the backfire arrestor to function properly: 
- should be</span><span> clean and undamaged.
- If there is a hole in the grid, or oil or gasoline in the grid, or if it is not properly attached, the arrestor will not work correctly.
- must be approved </span><span>by the U.S. Coast Guard</span>

If the temperature of a volume of ideal gas increases for 100°C to 200°C, what happens to the average kinetic energy of the mole
mina [271]

Answer:\Delta E=2.0715\times 10^{-21} J

Explanation:

Given

Temperature of the gas is increased from 100 to 200

Also we know that average kinetic energy of the molecules is

E=\frac{3}{2}\cdot \frac{R}{N_A}T

Where

R=Gas constant

N_A=Avogadro's number

T=Temperature in kelvin

\frac{R}{N_A}=1.381\times 10^{-23}

So kinetic energy increases by

\Delta E=\frac{3}{2}\times 1.381\times 10^{-23}\left ( 200-100\right )

\Delta E=2.0715\times 10^{-21} J
