If the temperature is 2∘C, then it will be ____.
Very hot
Hot
Cold
Warm
The freezing temperature is 0∘C. Hence, the temperature of 2∘C will be very cold.
The temperature of a gas at pressure P and volume V is 27∘C. Keeping its volume constant if its temperature is raised to 927∘C, then its pressure will be
NH3 can be liquefied at ordinary temperature without the application of pressure, but O2 cannot, because
The volume of a gas at 200∘C is 200 ml. If the temperature is reduced to −20∘C at constant pressure, its volume will be
If pressure is doubled at the same absolute temperature on 2L of CO2, then the final volume of CO2 will be
