1)Daniel should use a wooden spatula instead of a metal spatula because wood is a poor conductor of heat compared to metal. This means that the wooden spatula will not get as hot as a metal spatula when exposed to the hot soup, making it less likely to burn Daniel's hand or melt.
2)Devices that change electrical energy into light energy include incandescent bulbs, fluorescent lamps, and LED lights. Devices that change electrical energy into heat include electric stoves, water heaters, and hair dryers.
3)Some forms of energy that can be produced by using electricity, other than heat or light, include sound energy (produced by speakers or buzzers), mechanical energy (produced by motors), and chemical energy (produced by batteries or electrolysis).
4)Three things that can be done at home to conserve electricity and decrease the electric bill include: (1) turning off lights and unplugging electronics when not in use, (2) using energy-efficient appliances and light bulbs, and (3) adjusting the thermostat to reduce heating and cooling costs.
5)Three safety measures that must be observed when using electricity or heat include: (1) keeping flammable objects away from heat sources, (2) using electrical outlets and cords that are in good condition and not damaged, and (3) avoiding contact with water when using electrical devices.
