Answer:

If the Kelvin temperature of a gas is increased, the volume of the gas increases. This can be understood by imagining the particles of gas in the container moving with a greater energy when the temperature is increased.

Explanation:

If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure. Conversely if you cool the molecules down they will slow and the pressure will be decreased.

To calculate a change in pressure or temperature using Gay Lussac's Law.

What are the effects of gravity on earth?​
Sliva [168]

Answer:

Without it, we could not survive on Earth. Earth orbits the sun due to the gravity of the sun, which maintains us at a convenient distance from it to enjoy the sun's warmth and light. It keeps the air we need to breathe and our atmosphere in place. Our planet is held together by gravity.

Two cylindrical resistors are made from same material and have the same length. When connected across the same battery, one diss
Ilia_Sergeevich [38]

Answer:

\frac{d_2}{d_1} = \sqrt2 = 1.41

Explanation:

As resistor is connected to the battery of constant EMF then the power across the resistor is given as

P = \frac{E^2}{R}

now if two resistors are made up of same material and of same length then due to different cross sectional area they both have different resistance

Due to different resistance they both will have different power

Since power is inversely depends on the resistance

So if the power is twice that of the other then the resistance must be half

so we have

R_1 = \rho \frac{L}{A_1}

R_2 = \rho\frac{L}{A_2}

since one resistance is half that of other resistance

So the area of one must be twice that of other

so we have

\frac{A_2}{A_1} = 2

\frac{\pi d_2^2}{\pi d_1^2} = 2

d_2 = 1.41 d_1
