A volume of gas starts at a pressure of 10 atmospheres (atm) and a temperature of 47°C. If the temperature is increased by 1°C and the volume of the gas remains constant, what is the new pressure?
Answers
Answer:
V f = 22.7 L.
the volume of the gas decreases by one-half.
When the volume decreases, the pressure increases
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure
1 atm = 760 torr = 760 mmHg. n = number of moles, measured in moles (recall 1 mole = 6.022x1023 molecules), abbreviated mol. T = temperature, usually measured in degrees Kelvin, abbreviated K. 273 K = 0oC, and the size of 1 degree K is the same as the size of 1 degree C.
length × width × height.
highly recommended), express n in moles, R is the universal gas constant R=8.314Jmol−K , T is the temperature in Kelvins, and the volume V is in m3 . The resulting pressure P will be in Pa. R=0.082054L−atmmol−K , in which case the pressure is calculated in atm.
