Statement-1: Machine parts are jammed in winter.
Statement-2: The viscosity of lubricant used in machine part decrease at low temperature.

Machine parts are jammed in winter. Why?

Machine parts are jammed in winter due to

Statement I: Glass corners turns smooth when heated below melting point Statement II: Viscosity of glass is decreases with temperarue

Statement-1: If an annular disk is heated uniformly then outer radius increases but inner radius decreases. Statement-2: Temperature gradient of a rod is constant in steady state. Staement-3: Density of metal decreases with increase in temperature.

Statement-1 : Pendulum clocks go slow in summer and fast in winter. Statement-2 : The length of the pendulum used in clock increases in summer.

Statement-1: Coefficient of viscosity of liquid decreases while that of a gas increase, with increasing temperature. Statement-2: Density of a liquid and tht of a gas vary opposite manner with increase in temperature.

Statement-1: Specific heat capacities of all substance approach zero as T to O Statement-2: Molecular motion ceases at very low temperature.
