Keeping Warm Aim My aim of this investigation is to discover which insulating material is the most efficient for keeping warm. Background information An insulator is a material which helps prevent heat loss therefore keeping an object warm. Insulators protect against three types of heat loss: 1. Convection 2. Conduction 3. Infra red radiation. Convection best occurs in liquids and gasses. Hot air and water rises, e.g. when a pot of water is placed on a stove, the water at the bottom gets heated and becomes less dense, so moves upwards and is replaced by the colder water. To prevent this happening in my experiment I will cover the top of the beaker with a lid. This will stop most of the heat escaping from the top but not all of it, and therefore affecting the result of my experiment on insulation. To prevent minor heat loss from the bottom, I will place the beaker on top...
