PV = nRT
P = nRT/V = (1.2)(0.0821)(293)/9.5
P = 3.04 atmospheres
Units are: P = atmospheres; n = moles; R = L-atm/deg-mole; T= deg K; V = liters
The temperature of the glass become also 10 0C.

The absolute temperature must be doubled. (20'C + 273.15) = 293.15K. Doubled... (2) x (293.15) = 586.3K. (586.3K - 273.15) = 313.15'C. It must reach a temperature of 313.15'C in order to double the pressure.
To solve, use the combined gas law: (P1V1/T1) = (P2V2/T2). Plug in the initial conditions (P1 = 420 mm Hg, V1 = 500 mL, T1 = 20°C), and the final conditions (P2 = 650 mm Hg, T2 = 80°C) to find V2, the final volume. Remember to convert temperatures to Kelvin by adding 273 to the Celsius temperature.
The height of a water column that extends above the point of measurement affects the water pressure at that point. This height, also known as head, is commonly measured in feet or meters and represents the potential energy available to create pressure. The higher the head, the greater the water pressure.
At 20°C and one atmosphere of pressure, helium is not a solid. Helium exists as a gas at this temperature and pressure.
The equal volume of air that is twice as hot would have a temperature of 20C. Temperature is directly proportional to the average kinetic energy of the air molecules, so doubling the temperature would double the kinetic energy of the molecules.
A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20C to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5C. Assume that no gas escapes from the balloon during the flight. What is the volume of the balloon in Boston, relative to its size in Denver
20c
At standard temperature (20C) and pressure, pure H2SO4 is in a liquid state.
about 20c and 30c
The sample of water that has the lowest vapor pressure is the sample at a lower temperature. Vapor pressure decreases as temperature decreases because fewer molecules have enough energy to escape into the gas phase.
68F=20C

The vapor pressure (in mmHg) of acetic acid at 20C is approx. 26.
-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
