Science 8 - Quarter 1 - Module 6: Heat and Temperature Activity 1. Heat and Temperature. Complete each statement using a term or terms from the list below. Celsius expands higher temperature Joules how fast molecules vibrate less internal energy lower temperature more internal energy the number of molecules calories Fahrenheit Kelvin HEAT VS TEMPERATURE Heat and temperature are related but they are not the same. Heat depends on (1) and also on (2) that vibrate. More vibrating molecules usually mean (3) . Fewer vibrating molecules usually mean (4) _ Faster vibrating molecules mean (5). Slower vibrating molecules mean (6) Heat is measured in units called (7) and (8) Temperature is measured in units called (9) (10) and (11) When the matter is heated, it (12) Activity 2. Write TRUE if the statement is correct and FALSE if the statement is wrong. 1. Heat depends only on how fast molecules vibrate. 2. Joule is a unit of heat energy. 3. We measure temperature with a thermometer. 4. The faster molecules vibrate, the more heat they give off. 5. Temperature measures the average kinetic energy per molecule. Activity 3. Units of Temperature. Answer the questions below. Write your answers on a separate sheet of paper. 1. Study the figure below that shows thermometers in different temperature scales. 373 100 212 Boiling point of water at sea level 363 06 194 353 176 343 158 393 - 60 140 136*F (58*C) Highest temperature 323 50 122 recorded in world 313 40 104 A hot day 303 30 86 Average body temperature 98.6.F (37*C) 293 68 Average room temperature 283 Freezing (molting) point of water (ice) at sea level 14 -4 - 22 A bitter cold day 40 - 58 76 -91 112 183 130 -125.F ( - 87*C) Lowest temperature 173 148 recorded in world 2.
