9:37 ® d y LABORATORY-ACTIVITY-4 - Saved 目 LABORATORY ACTIVITY 4 PHYSICAL PROPERTIES OF MATTER I. OVERVIEW A physical property is a characteristic that can be observed and measured without changing the identity and composition of the substance. Examples of physical properties are color, melting point, and boiling point. Physical properties are very important because these help chemists in identifying substances. For example, a clear, colorless liquid observed to boil at 100 and freeze at OE would definitely be water. Water undergoes physical change wherein its physical appearance changes but its composition remains unchanged. I. ОВIЕСTIVES 1. To be able to determine the physical properties of matter. III.

You have substance X which is very flammable and substance Y which is very combustible in your garage in containers right in front of where you park your car. It is a hot July afternoon, 119Fand you just come home from work where your car was parked outside in the sun for 8 hrs and you were running the air conditioning the entire way home (hence, the car is very hot and is giving off a lot of heat). Which substance would you be more worried about and why ?
7. A methanol powered car produces CO₂ when it runs. Does that mean it is contributing to global warming? (A) No, if the methanol was produced from recently living biomass (B) Yes, if the methanol was produced from recently living biomass (C) Yes, if the methanol was produced from solar power (D) No, if the methanol was produced from natural gas. 8. The density of compressed natural gas is 60 grams per liter. If a car were powered by an engine that burned natural gas (similar to a gasoline engine), how large a compressed natural gas tank would it need to have the same range as a standard gasoline car? (A) about 3 times bigger than a standard car's gasoline tank (B) about the same as a standard car's gasoline tank (C) about 20 times bigger than a standard car's gasoline tank (D) about 10 times bigger than a standard car's gasoline tank
