True Or false
1. We all have sometime or other scalded our tongue while drinking a cup of hot, tea, coffee, soup or food. so it's true
2. A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.so it's true
3.When a substance changes state, the mass of the substance does not change. When a substance dissolves in a liquid, the total mass of the ... so it false
4. Metal conducts heat faster than wood — if the head of the ... Slightly longer: in general, materials are divided into ... When is it best to use a wooden spoon for cooking so it's true
5. Convection is by far the most efficient and common way for heat to be transferred through liquids and gases. It occurs when some regions of a fluid get hotter than others, causing currents in the fluid that move it around to distribute that heat more evenly. so it's true
