If a cup of coffee is at 90 times degree C and a person with a body temperature of 36 times degree C touches it, how will heat flow between them?

Heat flows from a warmer object to a cooler object when they touch. The coffee is at 90°C, while the hand is at 36°C, so heat flows from the cup to the hand. Therefore, the correct choice is “from the cup to the hand.”
