Answer:
1.When you pour hot water into a glass (which is at room temperature), the inner layer of the glass will absorb heat. When a material absorbs heat, it expands. ... (i.e. The inner layer of the glass will expand.) Since glass is not a good conductor of heat, the conduction of heat through the glass layer is slow.
2.Heat is transferred by three different methods: conduction, convection, and radiation.
3.If a metal spoon is dipped into a cup of hot water, the end of the spoon soon feels warm. Heat is transferred along the spoon by conduction. When a point on an object is heated, the molecules there vibrate more strongly. Conduction is the transfer of these vibrations within the material.
4.Because this process of transferring energy by direct contact is called conduction. Cooling things by conduction works the same way as warming. This time, a hot metal spoon is put in room-temperature water. The faster-moving atoms in the spoon contact the slower-moving molecules in the water.
