Class X If resistance of a metal wire at ice point is 500 Ω and 510 Ω at steam point, and resistance of wire is 502 Ω room temperature would be 10 °C 20 °C 30 °C 40 °C Kinetic energy is Directly proportional to temperature Inversely proportional to temperature Directly proportional to friction Inversely proportional to heat Boiling point of mercury is 630 K, which is equal to 357 °C −357 °C 84 °C −84 °C Process in which thermal energy is transferred without any flow of medium is termed as Conduction Convection Radiation Conduction and radiation both Moment of force is equal to F/d, where F is force and d is distance F + d, where F is force and d is distance F*d, where F is force and d is distance F - d, where F is force and d is distance Do you really want to submit this quiz?
