What happens to volume if the temperature of a gas is decreased from 60 degrees Celsius to 30 degrees Celsius?
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.

What happens at 0 degrees Celsius to 3 degrees Celsius?
At 0 degrees Celsius, water freezes and solidifies into ice. Between 0 and 3 degrees Celsius, the water remains in a partially frozen state with some ice crystals forming while the remaining water stays in liquid form.
What happens if you add 200 ml of water at 20 degrees Celsius to another 200 ml of water at the same temperature?
The final temperature will be 20 degrees Celsius, as the two volumes of water are at the same temperature. The total volume of water will be 400 ml.
What happens when an iron ball of 40 degrees Celsius is put in water of 40 degrees Celsius?
When an iron ball at 40 degrees Celsius is put into water at 40 degrees Celsius, heat will not flow from one object to the other since they are already at the same temperature. The iron ball and the water will reach thermal equilibrium, meaning they will both settle at the same temperature of 40 degrees Celsius without any change in temperature.
What happens to lead when its heated from 0-2000 degrees celsius?
Lead undergoes a phase transition from solid to liquid as it reaches its melting point of 327.5 degrees Celsius. As the temperature increases further, the liquid lead will eventually vaporize into a gas at around 1750 degrees Celsius.
What is the average body temperature for cattle?
This all depends on the breed. European breeds have a comfort zone between 20 degrees Celsius and -20 degrees Celsius. Brahmans, however, have a comfort zone between 30 degrees Celsius and -10 degree Celsius. Brahman-European crossbreds are in between.
What happens 0 C on the celsius temperature scale?
Water freezes at 0 degrees Celsius and at 32 degrees Fahrenheit.
What is the temperature of 100 Celsius in degrees?
100 degrees Celsius is the boiling point of water, which happens to be 212 degrees Fahrenheit at standard pressure
What happens to the mass of gas when temperature is decreased by -273 degree celsius?
The Mass of a substance will not change with a reduction of temperature … even to -273C.
What happens to water at 1 ATM preassure as the temperature is decreased from 10 degrees to -10 degrees?
It depends on the temperature scale being used.
What happens when sulphur is at 115 degrees?
At 115 degrees Celsius, sulfur will change from a solid state to a liquid state. This temperature is above the melting point of sulfur, which is around 112.8 degrees Celsius.
What is the temperature in degrees Fahrenheit when the temperature is - 40 degrees celsius?
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5) C + 32 It's funny but it's true. It happens that -40 degrees Celsius is -40 degrees Fahrenheit.
What happens at 0 degrees Celsius?
At 0 degrees Celsius, water freezes and turns into solid ice. This is the temperature at which liquid water transitions to a solid state.
What happens to temperature above 0 degrees?
As temperature rises above 0 degrees Celsius, water transitions from a solid (ice) to a liquid state. This process is called melting.
What happens to a water at a temperature of 20 degree celsius when it is placed into a freezer set at -10 degree celsius?
When the water at 20 degrees Celsius is placed in a freezer set at -10 degrees Celsius, the water will begin to lose heat to the surroundings. As a result, the temperature of the water will decrease until it reaches the equilibrium temperature of -10 degrees Celsius. At this point, the water will freeze and turn into ice.
Room temperature in celsius?
Room temperature depends on whatever temperature the room happens to be, but the generally accepted temperature for "room temperature" is roughly 70ºF, or about 21ºC. To calculate Celsius from Fahrenheit you subtract 32 from the degrees Fahrenheit, multiply this number by 5, and then divide that number by 9.
How much is -40F in degrees celsius?
Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit. Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit.
What happens if you heat the steam above 100 degrees celsius?
If you heat steam above 100 degrees Celsius, it will continue to increase in temperature without changing to water. This is because steam is already in a gaseous state at temperatures above 100 degrees Celsius.
