How do you find pressure from specific volume and temperature?
Specific Volume Formulasν = V / m where V is volume and m is mass.ν = 1 /ρ = ρ-1 where ρ is density.ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity..
Does hot water or cold water weigh more?
When water freezes, however, it expands, becoming less dense. If equal volumes of cold water (down to 4deg. C, 39.2deg. F) and hot water are compared, cold water weighs more than hot water.
How does volume change with temperature?
1) If the volume of a container is increased, the temperature increases. 2) If the volume of a container is decreased, the temperature decreases. This means that the volume of a gas is directly proportional to its temperature. … If you heat a gas you give the molecules more energy so they move faster.
Does water weight change with temperature?
Weight depends on density (think of a helium balloon). Water has different density depending on temperature (that’s why ice floats). As I remember, water at 4 degrees C is the densest. Therefore, yes, it’s weight is different at different temperatures.
Do hot things weigh more?
Yes. If you have absolutely identical objects that have the same weight exactly when they are at the same temperature, then when one object is heated, it will weigh more. This is because the gravitational force depends on the stress energy tensor in general relativity.
What happens to pressure when volume increases?
Boyle’s law states that for a fixed amount of gas in an enclosed system at constant temperature, pressure and volume are inversely proportional. … So if the volume increases, the pressure decreases. This makes sense if you think of a balloon of any gas.
Does specific volume change with temperature?
Specific volume is inversely proportional to density. If the density of a substance doubles, its specific volume, as expressed in the same base units, is cut in half. … As stated above, specific volume varies noticeably with changes in temperature while the gas phase.
Why does a larger volume of water take longer to cool?
Your larger body of water, simply due to the fact that there’s more of it, has more heat energy. It’ll take longer to cool, even though it’s losing heat faster.
What is the difference between density and specific volume?
The specific volume of a substance is defined as the volume per unit mass. Typically specific volume uses the symbol v. The density of a substance is defined as the mass per unit volume, and it is therefore the reciprocal of the specific volume. … Density is defined as mass per unit volume.
How much does the volume of water change with temperature?
In general, the liquids tend to expand when their temperature increases. For example, the same mass of boiling water occupies more volume at 100 degrees Celsius than at 20 degrees Celsius. Therefore, increasing temperature decreases density. Answer C is correct.
Why does a larger volume of water take longer to heat up?
Compared to air or land, water is a slow conductor of heat. That means it needs to gain more energy than a comparable amount of air or land to increase its temperature. … That means that, once heated, a body of water will hold onto that heat for a much longer period of time than either air or land.
How does temperature affect gas volume?
This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand.
How do you find a specific volume?
To calculate specific volume you need to know the volume (V) and the mass (m). Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.
Is hot or cold air heavier?
Cold air is always heavier than an equal volume of hot air. “Air” is actually a mixture of several gases.
