Which body will give a greater amount of heat: mercury in a thermometer or mercury in a bottle with a volume of 0.5 l when lowering their temperature by 2 ° C?
When cooled, the body gives off the amount of heat defined by the formula Q = mcΔt. Since in both cases the substance is mercury, and the temperature difference is the same, the amount of heat will depend only on body weight. Since the mass of mercury in the bottle is much greater than in the thermometer, more heat will be transferred.
