# One gram of water at 4 degrees Celsius occipes a volume of approximately?

1 cm3 (or 1 mL, they are equivalent)

### A volume of air has a temperature of 0 degrees Celsius An equal volume of air that is twice as hot has a temperature of about what?

Since 0 degrees Celsius equals 273 degrees Kelvin, then air that is twice as hot would be equal to 546 degrees Kelvin, which when converted back to Celsius is equal to 273 degrees Celsius. The natural urge is to double the Celsius temperature, let's say it was 5 degrees Celsius, then you'd probably want to double it to 10 degrees Celsius, however, that isn't correct. True temperature is measured in Kelvins, so you must convert…

### How is absolute zero originally determined?

The volume of gases decreases with temperature; extrapolating the volume/temperature relationship, it looked as if all gases would reach a volume of zero at approximately the same temperature, about minus 273 degrees centigrade. The volume of gases decreases with temperature; extrapolating the volume/temperature relationship, it looked as if all gases would reach a volume of zero at approximately the same temperature, about minus 273 degrees centigrade.

### A gas at 50 degrees Celsius has a volume of 50ml if you increase the temperature to 80 degrees celsius what will its volume be?

Using the Ideal Gas Law, PV = nRT Solve for n. n = PV/RT = (101.325 kPa)(0.050 L)/(8.314)(323K) = 0.001886575 mol Now we know the number of moles of the gas at 50 degrees Celsius (323 Kelvin). What we need to do now is to solve for the volume at 80 degrees Celsius (353 Kelvin). V = nRT/P = (0.001886575 mol)(8.314)(353K)/(101.325 kPa) = 0.546 mol Can you please tell me if this is correct?

### What is the volume of 0.625 mol of nitrogen at 74.2 kPa and 85 degrees celsius?

The volume of 0.625 mol of nitrogen at 74.2 kPa and 85 degrees Celsius can be calculated using the formula Volume equals moles times gas constant times temperature divided by pressure. The gas constant is .08296 Latm/molK, 74.2 kPA in atm is .732, and 85 Celsius in kelvin is 358.15. The final result is 25.08 liters.

### Between 4 degrees Celsius and 0 degrees Celsius water particles form little what?

crystalline structures that tend to collapse when 0 degrees celsiurs in increased. The melting of these crystals further decreases the volume of the water. The water undergoes two processes at the same time- contraction and expansion. Volume tends to decrease as ice crystals collapse, while volume tends to increase due to great molecular motion

### If you have mL degrees Celsius and mmHg figure out Volume at STP?

That's going to depend on the substance, which the question neglects to identify. --------------------------------------------------- The volume of any gas at STP (pressure of 1 ATM & temp.: 0oC) is approximately 22.41 L/mol or 22,410 mL/mol. So you need to find out how much gas you have to begin with (# of moles) to find the volume of the gas at STP.

### What does it mean that absolute zero decreases by 1 over 273 volumes per degree?

The way you state it, it is confusing. Absolute zero is a fixed temperature; therefore it doesn't increase or decrease. The volume of a gas will increase or decrease with pressure. The change in volume is such that if you extrapolate, it should theoretically have a volume of zero at approximately minus 273 degrees (Centigrade). The way you state it, it is confusing. Absolute zero is a fixed temperature; therefore it doesn't increase or decrease…

### The volume of 4 cubic meters of gas is kept under constant pressure Its temperature is increased from a minus 73 degrees Celsius to 127 degrees Celsius What is the new volume of the gas?

pV = nRT p = pressure V = volume n = number of moles R = gas constant T = temperature (in Kelvin) In this case, the number of moles remains the same, as does the gas constant (it IS a constant, after all) and pressure. The only things changing are the volume and temperature. This simplifies the equation to: 4 cubic meters gas = 200 K (-73 degrees celsius) Therfore: 200K/4 = 400K/x x…

### Can a sample of water possibly have the same volume after being warmed by several degrees Celsius?

Under very specific conditions - yes, but normally no. Except in a narrow range from about 0° to about 8 °C, a sample of water can only have the same volume after being warmed by several degrees Celsius if it is confined in a fixed volume container. Liquid water is slightly compressible so if you place it inside a container where it can be compressed, you can heat it a few degrees Celsius and still…
