The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
At 1 ATM of pressure water boils at 100 C if the sample was placed under 2.5 ATM of pressure what would be the temperature?
(P at 1 atm)/(P at 2.5 atm)=(100+273)/Temperature at 2.5 atm932.5 k
What does the state of a sample of matter depend on?
The four classical phase changes in matter depend on pressure and temperature. Solids need the lowest amount of pressure and temperature, followed by liquid, then gas, then plasma needing the most. (There are other non-classical states of matter eg. superfluids) The amount of temperature and pressure (or just enthalpy) required to make the phase change depends on the molecular structure of the molecules.
A 175 mL sample of neon had its pressure changed from 75kPa to 150kPa what is its new volume if temperature is held constant?
240 Assuming ideal gas behavior, doubling the pressure means reducing the volume by a factor of 2.
What temperature must a urine sample be?
urine sample should be between 98-100 degrees F, I got this info at a store that sells pass urineproducts test
Is it true that the temperature of a sample of steam increases from 100 to 200. The average kinetic energy of its particles doubles?
False
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
In which physical state will a sample of a 100 grams of water contain the most energy?
100 g Steam at high temperature (>100°C) and pressure (>1 Bar)
At 1 ATM of pressure water boils at 100 C if the sample was placed under 2.5 ATM of pressure what would be the temperature?
(P at 1 atm)/(P at 2.5 atm)=(100+273)/Temperature at 2.5 atm932.5 k
What is the density of 100 gram of water?
The density of water at standard temperature and pressure is 1 gram/milliliter. The size of the sample is irrelevant. If the sample is pure, then one drop of it has the same density as a tankerful of it has.

A sample of water under study was found to boil at 102 degrees celsius at normal temperature and pressure is the water pure?
No. Pure water boils at 100 degrees Celsius or less.
What happens to boiling water if the pressure increases or decreases?
water boils when the vapour pressure becomes equal to the external pressure. So if we increase the pressure, the rate of boiling will increase. Think of the vapor pressure as the pressure that is needed to force a bubble to the surface.it lowers

How many liters are in 100 grams of water?
The density of water at standard temperature and pressure is 1 gram/milliliter. The size of the sample is irrelevant. If the sample is pure, then one drop of it has the same density as a tankerful of it has.
Would a sample of gas in a closed container in space exert pressure on the sides of the container if the gas was kept at standard temperature and pressure?
Even if the pressure inside a container is equal to the pressure outside a container, there is still pressure. It's like pushing a friend one way while he pushes you back. Neither of you may be moving, but you're still pushing. The sample of gas would exert exactly one atmosphere of pressure (or 100 kPa) on the container. The question then becomes whether the container can withstand that pressure.
State the relationship between water temperature and the maximum mass of ammonium chloride that can be dissolved in 100 grams of water?
As the temperature of the water increases, the amount of solute (in this case NH4Cl) that can be dissolved increases.
