Two students discuss why a metal chair feels colder than other objects in the room.   Student 1: Since feeling cold is just about temperature, the metal chair must have a lower temperature than anything else in the room. That’s why it feels colder.   Student 2: Feeling cold isn’t just about temperature, it’s about how quickly you’re losing heat. If the chair feels colder, it must be taking your heat faster.     Which of these students, if any, do you agree with? Explain your reasoning.
