A cylinder of compressed gas has a pressure of 488.2 kPa. The next day the cylinder of gas has a
Luda [366]

Answer:

20 °C

Explanation:

Ideal gas law:

PV = nRT

Rearranging:

P / T = nR / V

Since n, R, and V are constant:

P₁ / T₁ = P₂ / T₂

488.2 kPa / T = 468 kPa / 281.15 K

T = 293.29 K

T = 20.1 °C

Rounded, the temperature was 20 °C.

coldgirl [10]

Answer:

No. Tension Force Elastic Force

1. A force transmitted through a wire, rope or a string when it is pulled from opposite ends is known as a tension force. A force that allows an object to return its original shape after being stretched or compressed is known as an elastic force.

2. Example: Pulling a rope from two opposite ends

When a rope is pulled from two opposite ends, a tension is generated in rope.

Due to this tension, a force is transmitted through a rope which is known as a tension force. Example: Stretching a rubber band

When a rubber band is stretched, it gets stretched easily due to its elastic nature.

The more a rubber band is stretched, the more force it will exert to return back to its original shape.

This force is known as an elastic force.
