Answer for Q1 - Looks correct - But the arrows must be within the water. You have marked outside the water. (refer to the attachment.

Answer for Q2 - Metals are good conductors of heat and non-metals and gases are usually poor conductors. Poor conductors are called insulators. Heat energy is conducted from the hot end of an object to the cold end. The atoms/molecules are fixed in place but are free to vibrate. When part of a solid absorbs heat, the atoms/molecules vibrate faster. These vibrations are passed from atoms/molecules to atoms/molecules thus transferring heat.
