There is not enough information given. The pressure of a gas in atms equals the number of moles times the kelvin temperature times the 'R' constant (0.0821) divided by the volume. Shorthand, P = nRT/V
Pressure of a gas depends on more than volume. You must also know the temperature and the amount of gas in moles.
PV = nRT is the equation for the Ideal Gas law. R is a constant (like pi for circles).
so if you know all the variable conditions in the equation except pressure, you can solve for pressure.
The Boyle-Mariotte law:
pV = k at constant temperature
The meaning is: if the container with gas is tightly closed and the temperature remain constant the pressure remain unchanged.
At 60 cm volume the pressure of gas would be 120000 pascals.
The volume is 20 m3.
The pressure in at is 0,0041.K.
25 g/cm3 x 60 cm3 = 1500 g
p1.V1 / T1 = constant = p2.V2 / T2 (the 'Boyle&Gay-Lussac' Law)250*15/100 = 500*30/ T2T2 = 400K
Volume = 3 cm x 2 cm x 10 cm = 60 cm3 Mass of 60 cm3 water = 60 grams Mass of box + contents would be >60 gramsbefore it could sink.
The volume of the gas will decrease. The gas molecules move faster when they are warmer, because more heat equates to more energy. The faster they move, the more space they will take up and the greater the volume. Therefore, if the temperature goes down, they have less energy and take up less space. This is shown in the ideal gas law: PV = nRT P = Pressure of the gas V = Volume n = mols of the gas R = ideal gas constant (8.314 J/molK) T = Temperature As you can see, if temperature is decreased and only pressure is allowed to change, with all other variables remaining constant, volume will also have to decrease to maintain the proportion.
0.737 kg. The answer is correct but i tell the calculation density=mass/volume density of petrol at 60*f=737.22 kg/cm3 1 litre=1000 cm3 (1 cm3=1/1000 litre) 737.22(kg/cm3)=mass(kg)/volume(cm3) 737.22(kg/cm3) * volume(cm3)=mass 737.22 * (1/1000 litre)=mass(kg) 0.737 kg=mass There is no conversion. One is volume and the other is mass or weight.
25 g/cm3 x 60 cm3 = 1500 g
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.
10*3*2 = 60 cm3
60
You will mean 15 cc or cubic centimeter. The answer is 4g / cc ( 60 g divide 15 cc )
5*3*4 = 60 cm3
Volume of cube = 2*2*2 = 8 cm3 Volume of cuboid = 10*6*8 = 480 cm3 So number of cubes in cuboid = 480/8 = 60
p1.V1 / T1 = constant = p2.V2 / T2 (the 'Boyle&Gay-Lussac' Law)250*15/100 = 500*30/ T2T2 = 400K
Volume = 3 cm x 2 cm x 10 cm = 60 cm3 Mass of 60 cm3 water = 60 grams Mass of box + contents would be >60 gramsbefore it could sink.
depth = 3000/(100*60) = 0.5 cm 3000 cm3 = 3 liters total capacity = 100*60*40 = 240000 cm3 = 240 liters
