A: Machine parts are jammed in winter.
R: The viscosity of lubricant used in machine parts increase at low temperature.

View answer and explanation

Correct option: A

Both A and R are true and R is the correct explanation of A

Option A (Both A and R are true and R is the correct explanation of A) is correct because the viscosity of lubricants increases at low temperatures, causing machine parts to jam.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
