Answer:
The answer is below
Explanation:
A diver works in the sea on a day when the atmospheric pressure is 101 kPa. The diver uses compressed air to breathe under water. 1700 litres of air from the atmosphere is compressed into a 12-litre gas cylinder. The compressed air quickly cools to its original temperature. Calculate the pressure of the air in the cylinder.
Solution:
Boyles law states that the volume of a given gas is inversely proportional to the pressure exerted by the gas, provided that the temperature is constant.
That is:
P ∝ 1/V; PV = constant
P₁V₁ = P₂V₂
Given that P₁ = initial pressure = 101 kPa, V₁ = initial volume = 1700 L, P₂ = cylinder pressure, V₂ = cylinder volume = 12 L. Hence:
P₁V₁ = P₂V₂
100 kPa * 1700 L = P₂ * 12 L
P₂ = (100 kPa * 1700 L) / 12 L
P₂ = 14308 kPa
Answer:
C.
Explanation:
A meter is 8.56 centimeters longer than a yard. Something to keep in mind is that a meter is about 10% longer than a yard.
Hope this helps :)
A) all because of the movement, and friction involved with the movement.

Answer:
Fusion is the change of phase from: solid to liquid.
Explanation:
Fusion is defined as change of of a substance from solid state to liquid state.Also known as melting.
Solid → liquid (Fusion)
Vaporization is defined as change of of a substance from liquid state to gaseous state.
liquid → gas (vaporization)
Freezing is defined as change of of a substance from liquid state to solid state.
liquid → solid (solidification)
Deposition is defined as change of of a substance from gaseous state to solid state.Also known as melting.
Gas→ solid (deposition)
Sublimation is defined as change of of a substance from solid state to gaseous state.Also known as melting.
Solid → gas (sublimation)
Condensation is defined as change of of a substance from gaseous state to solid state.Also known as melting.
Gas→ liquid (Condensation)
