Which changes in pressure and temperature occur as a given mass of gas at 380 torr and 546 K is changed to STP known?

The pressure is doubled (up to SP=760 Torr) and the temperature is halved (down to ST=273 K) as long as the volume (and amount of matter) is UNchanged!

What is the volume occupied by 26.9g of argon gas at a pressure of 1.23 and a temperature of 374?
The question cannot be answered because there are no units given for the pressure not temperature.
What do air density and air pressure have in common?
At a given temperature, the higher the air density, the higher the air pressure.
Vapor pressure is measured when a liquid and its vapor are?
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure
What will increase the volume of gas?
change the pressure and/or the temperature of the gas
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
What is the melting point of an element?
It is the temperature at which the element will change state from a solid into a liquid. Note that the temperature actually changes depending on pressure. When no pressure is given assume 1 atmosphere.
How does the presence of water affect the melting temperature of a rock?
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.

Do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.

Pressure changes ocurring over a given distance?
Pressure Gradient
What name is given to the processes whereby the temperature of the air changes without the addition or subtraction of heat?
Adiabatic temperature changes
Which area undergoes large changes in temperature in a given day?
tundra
What happens to a gas temperature at a given pressure?
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
What is the concentraction of the solution?
Concentration is the amount of a solute in a given volume of solution at a given temperature and pressure.
What is the amount of salt in a substance?
This is called the solubility at a given temperature and pressure.
Does pure liquid boils at fixed temperature at a given pressure?
Yes
