Question

Ice cools down a drink because the ice is colder than the drink and heat flows into the ice cubes. heat is absorbed from the drink to melt the ice cubes. The heat of fusion of the fusion of the ice is higher than the heat of fusion of the water. Both A and B are correct. The absorption of light energy by green plants to synthesize starches is endothermic. Exothermic. isothermic. All of the above If the temperature of a gas is increased the pressure will decrease. The volume will increase. the volume will decrease. The number of molecules will increase. If two gases have the same volume. temperature, and pressure, they also have the same density number of molecules molar mass speed.

Explanation / Answer

5. Ice is cooler than drink. So here is absorbed haet from drink

D. B and A

6. A chemical reaction heat energy is absorbed . it is called endothermic reaction. So photosynthesis is edothermic reaction

A. endothermic

7. Volume is directly proportinal to temperature > Temperature is increases volume is increases.

B. the volume is increases

8. From avogadro's law

B. number of molecules
