A meta cube is plced in an empty vessel. When water is filed in the vessel so that the cubeis completely immersed in the water, the fore on the bottom of the vessel in contact with the cube

When two surface are polished, the friction coefficient between them decreases. But the friction coefficient increases and becomes very large if the surfaces are made highly smooth. Explain.

When ice melts to form water, change occurs in its

When we cool the water____is obtained

Take a few ice cubes in a glass. Keep it on the table for a few minutes. You could see tiny droplets of water all over the outer surface of the glass. From where do these droplets come?

Figure shows a large tank of water at a constant temperature theta_(0) and a small vessel containing a mass m of water at an initial temperature theta_1 (lt theta_(0)) . A metal rod of length L , area of cross section A and thermal conductivity K connects the two vessels. Find the time taken for the temperature of the water in the smaller vessel to become theta_(2) (theta_(1)lt theta_(2)lt theta_(0)) . Specific heat capacity of water is s and all other heat capacities are negligible.

Take a glass of water and put some ice cubes inte it. Observe it for some time. What happens? The ice cubes melt and disappear. Why did it happen?
