Heat is transmitted from higher to lower temperature through actual mass motion of the molecules in _____.

Water boils at lower temperature on higher altitudes because

Give reason: Phenols boil at higher temperature than arenes of comparable molecular mass:

The temperature of an ideal gas is increased from 140 K to 560 K.If at 140 K the root mean square velocity of the gas molecules is V, at 560 K it becomes:

Out of C and CO, which is a better reducing agent in the lower temperature range in the blast furnace to extract iron from the oxide ore?

The durations of mitotic stages in two situations. (A and B) are tabulated below. Following are some interpretations: 1. 'A' and 'B' indicate the same plant tissue grown at higher and lower temperature respectively. II. 'A' indicates a slow growing plant species and 'B' indicates a fast growing plant species. III. Both 'A' and 'B' indicate dormant plant tissues with excessively long interphase. The correct interpretations is/are

Equal masses of monoatomic and diatomic gases at the same temperature are given equal quantities of heat. Which gas undergo a larger temperature rise and why?
