Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
What happens to a gas heated in cylinder?
the gas expands and exerts more pressure on the sides of the cylinder. Basically, the pressure goes up due to a temperature increase.
What color does a container have to be for water to be heated as much as possible?
The colour of a container does not impact how hot water can be in it. Water boils at 100 C and the temperature rises no higher. Super hot water can only be produced in sealed high pressure vessels usually made of steel or similar material.
How do temperature changes affect pressure?
when something is being heated up, it expands increasing the pressure.
100.0 g of copper carbonate was heated until it decomposed completely the gas was collected and cooled to room temperature and normal pressure what volume of carbon dioxide was produced?
18 l ------------
150.0 g of copper carbonate was heated until it decomposed completely The gas was collected and cooled to room temperature and normal pressure What volume of carbon dioxide was produced?
29.7 L

What will happen to air if it is heated along a slope element?
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
How to increase a Thermal efficiency of rankine cycle?
-increase the temperature of the super heated steam -lowering the condensing pressure -increasing the boiler pressure (Reheating, regeneration...)

Why would an aerosol can blow up if it was placed in an hot oven?
An aerosol can contains compressed gas, which is already under pressure. If the gas is heated the pressure will increase, and if it heated a lot, the pressure will become great enough to cause an explosion. The connection between temperature and pressure comes about because temperature, on the molecular level, is determined by the speed at which the molecules are moving. And faster molecules have more energetic collisions, thereby exerting more pressure.
What happens to a gas heated in cylinder?
the gas expands and exerts more pressure on the sides of the cylinder. Basically, the pressure goes up due to a temperature increase.
What phases does a solid go through when heated?
Some materials have multiple solid phases, others do not. It depends on the particular material and also on the temperature and pressure conditions. If you want to know what phases a specific material at a particular pressure goes through as it is heated from temperature X to temperature Y, that would be answerable by looking at a phase diagram for that material, but the generic form cannot be answered.
What is the necessary temperature for a liquid to change to a gas?
It is called the boiling point. It varies according to the substance being heated and the ambient pressure
