The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
At high pressure the boiling point is higher.
Atmospheric pressure will decrease as altitude increases.
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Temperature increases as pressure increases.
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
as pressure increases, temperature increases
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
The pressure increases.
As pressure increases, temperature increases and volume decreases.
The temperature rises.
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
