The hotter liquid flows faster than the colder ones. Explain, why.

Water flows faster than honey. Why?

Warm water evaporates faster than cold water. Explain.

Hot syrup flows faster because

“Blue hot is hotter than red hot”. Explain.

In two experiments with a countinous flow calorimeter to determine the specific heat capacity of a liquid,an input power of 16 W produced a rise of 10 K in the liquid. When the power was doubled, the same temperature rise was achieved by making the rate of flow of liquid three times faster. Find the power lost (in W) to the surrounding in each case.

If we put our hands above a fire or at the side of the fire to get warmth in a winter night. It feels hotter above a fire than by its side. Explain.

Is DeltaH always greater than DeltaU ? Explain why or why not?

A copper tumbler feels much colder than a wooden block on a cold day. Explain why.
