Why does the volume of the water vapor increase and the mass remain constant When 1 gram of water is evaporated?
Mass is mass. It is constant. Changing water from liquid to gas does not change the mass, it only changes the density, which is mass per volume. Look at it another way - in gaseous form, the same mass of water has the same number of molecules of water - but those molecules are simply further apart.
What else can I help you with?
What happens to pressure when the temperature and volume is halved?
if kelvin temp is halved, the volume is halved if pressure is constant.
What would the effect on temperature and volume be if you changed the number of moles of gas in a container?
In a container the volume remain constant but the pressure increase.
What must remain constant for pressure and temperature to be directly proportional?
The volume of the gas must remain constant for pressure and temperature to be directly proportional, according to Boyle's Law. This means that as the pressure of a gas increases, its temperature will also increase proportionally, as long as the volume is held constant.
When does raising the temperature of a gas increase its preasure?
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
Does density increase decrease or stay the same if temp and mass of a liquid increase?
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
What happens to pressure when the temperature and volume is halved?
if kelvin temp is halved, the volume is halved if pressure is constant.
What happens to density if you change the volume and mass?
If you increase both the volume and mass of an object proportionally, the density will remain the same. However, if you increase the mass while keeping the volume constant, the density will increase. Likewise, if you increase the volume while keeping the mass constant, the density will decrease.
What would the effect on temperature and volume be if you changed the number of moles of gas in a container?
In a container the volume remain constant but the pressure increase.
When 1 gram of water is evaporated the volume of the water vapor increases but the mass remains constant Why does the mass of the water remain constant?
Mass never changes unless you add more to it, the volume actually stays the same but is more spread out.
What must remain constant for pressure and temperature to be directly proportional?
The volume of the gas must remain constant for pressure and temperature to be directly proportional, according to Boyle's Law. This means that as the pressure of a gas increases, its temperature will also increase proportionally, as long as the volume is held constant.
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
Explain why pressure increases as a gas is compressed into a smaller volume?
PV=nRT Where:- P=pressure V=volume n=number of moles R=gas constant T=temperature n,R and T all remain constant. So if volume is decreased, in order for the right hand side to remain a constant value, the value for pressure must increase.
When does raising the temperature of a gas increase its preasure?
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
Does density increase decrease or stay the same if temp and mass of a liquid increase?
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
Why does pressure increase with an increase in temperature?
PV=nRT where P=pressure, V=volume, n=no. of moles, R=gas constant, T=temperature(K) since volume and the number of moles remain constant, they can be ignored and we can assume:- that P is proportional to T and thus if temperature is increased, pressure will also increase.
If temperature increase and volume remain constant what is pressure?
If temperature increases while volume remains constant, according to Charles's Law, pressure will increase proportionally. This is because the increased temperature will cause the gas molecules to move faster and exert more force on the walls of the container, resulting in an increase in pressure.
How does the volume of an ideal gas at constant temperature and pressure change as the number of molecules increases?
The volume of an ideal gas will increase as the number of molecules increases at constant temperature and pressure. This relationship is described by Avogadro's law, which states that the volume of a gas is directly proportional to the number of molecules present, assuming constant temperature and pressure.
