A 25-liter sample of steam at 100°C and 1.0 atm is cooled to 25°C and expanded until the pressure is 19.71 mmHg. If no water condenses, calculate the final volume of the water vapor.
770 L
240 L
1.3 x 10-3 L
1.0 L

Weegy: A) 770 L
It will condense, because steam becomes liquid water below 100°C. User: A diesel engine's piston compresses 16 cm3 of fuel-air mixture into 1 cm3. The pressure changes from 1 atmosphere to 48 atmospheres. If the initial temperature of the gas was 305 K, what was the final temperature?
Note: As long as the units for pressure and volume are the same on both sides of the equation, they will cancel. Temperature, however, must be ... (More)

The mathematical formula for Boyle's Law is:
P/V = k
P1/V1= P2V2
P/T = k
P1V1 = k
PT = k

Weegy: The mathematical equation for Boyle's law is PV = k or you could say P1V1=P2V2.
P IS the pressure of the system.
V is the volume of the gas.
k is a constant value representative of the pressure and volume of the system. [
**It just states that pressure and volume are inversely proportional when temperature is held constant (does not change). In other words, as volume increases pressure decreases and vice-versa (when temperature is ... (More)

A tire has a pressure of 780 mmHg at 27°C. If the tire is heated to 47°C on hot pavement, the new pressure will be:
310 mmHg
280 mmHg
830 mmHg
590 mmHg
none of these

Weegy: 830 mmHg User: A 1.50-liter sample of dry air in a cylinder exerts a pressure of 3.0 atmospheres at a temperature of 25°C. Without change in temperature, a piston is moved in the cylinder until the pressure in the cylinder is reduced to 1.0 atmosphere. What is the volume of the gas? (Be sure to use the correct number of significant figures.)
0.22 L
0.50 L
2.0 L
4.5 L
Weegy: Answer is 4.5 L (More)
