A balloon contains 5.5 L of air at 303 K and 101.3 kPa After an hour the air inside the balloon cools to 297 K What is the final volume of the air in the balloon?
5.4L
Two cubic meters of a gas at 30 degrees Kelvin are heated at a constant pressure until the volume doubles. What is the final temperature of the gas?
60
What happens to the volume of air when it is heated?
The volume of air increases proportionally as it is heated, according to the formula: PV/T = P'V'/T' Where P, V, and T are initial values for pressure, volume and temperature in absolute terms and P',V',and T' are the final values with a constant pressure the equation becomes: V/T = V'/T' to solve for final volume the equation is: VT'/T = V' if V=1cu. meter, T = 200K and T' = 300K then 1 cu.meter x 300K/200K = 1.5 cu.meter
When a balloon is heated its volume doubles What is happens to its density?
The density decreases by half. You find the answer by knowing that density is equal to mass divided by the volume. If the mass stays constants and the volume is doubled, then the density is halved.
The pressure acting on 60 cubic meters of gas is raised from 236 kPa to 354 kPa The temperature is kept constant What new volume does the gas occupy?
8. Two cubic meters of a gas at 30 degrees Celsius are heated at a constant pressure until the volume doubles. What is the final temperature of the gas? 60.
What is the final volume of a balloon that was initially 500.0 mL at 25 degrees Celsius and was then heated to 50 degrees Celsius?
Change Celsius to Kelvin by adding 273.15. 25 C = 298.15 K 50 C = 323.15 K An equality. 500.0 ml/298.15 K = X ml/323.15 K 298.15X = 161575 X = 541.925 milliliters -------------------------------you do significant figures

How hot must the air in a balloon be heated if initially it has a volume of 750 L at 20 degrees celsius and the final volume must be 1000 L?
The way to keep this simple is to assume that the pressure in the balloon remains constant throughout the operation. The only trick to this whole thing is to understand that-- At constant pressure, volume is directly proportional to temperature.Volume2/Volume1 = Temperature2/Temperature1-- 'Temperature' means absolute temperature ... Kelvin, or (Celsius + 273).? The initial temperature of 20 C is absolute temp of 293 K.If the pressure remains constant, thenAbsolute-temp2 = Absolute-temp1 x (Volume2/Volume1) = 1,000 x 293/750 = 3902/3 K.°Celsius = Absolute - 273 = 117 2/3 ° C.

When a solid is heated and then pressed to form a new shape Is its area remains constant or volume or both?
Assuming that none of the solid evaporated during the time that it was being heated, then the mass must be conserved. Then, assuming that after the object is in its' final shape the density of the material returns to its' original value the volume must be unchanged. This is because mass = volume * density. However, the surface area does not have to be the same.
If 20.00mL of a 1.50M solution of KBr is diluted to a final volume of 150.0mL what is the new molar concentration?
initial molarity*initial volume= final molarity*final volume Initial molarity= 1.50M Initial volume= 20.00ml Final Volume=150.0ml Thus final molarity =1.50M*20ml/150ml=0.200M. New molar concentration= final molarity
How can you measure the volume of air inside a ballon?
Probably the simplest way would be to fill a container having a known volume (say, a 5 gallon bucket) with water right to the top, weigh it, then push the balloon under the water. The water displaced by the balloon will spill out. (Your hand will displace water too, which screws things up, so use something like a stick to push the balloon all the way in.) Now take the balloon out of the water and weigh the bucket again. The difference between the earlier weight and the final weight is the weight of the water that the balloon displaced. The density of water is 1 gram per cubic centimeter (cc), so (to a very good approximation) the volume of air in your balloon in cc is the same as the weight of the displaced water in grams.
