SOL Review #2

Iron has a higher specific heat than silver. If 1 kg of iron and 1 kg of silver absorbed equal amounts of heat, which element will increase to a higher temperature?

• Iron

• Silver

• Both silver and iron's temperature will increase at equal amounts.

• Neither silver or iron will absorb the heat, they reflect it.

Stacy is at a baseball game and reaches for a bottle of lemonade in her styrofoam cooler. As she grabs her drink, she wonders how it stayed cold so long when it is 90 degrees F outside. You help her answer the question by explaining the direction of heat transfer and what is preventing the transfer. Which one of the answers below best fits your explanation?

• Heat will transfer from the outside air into the cooler. The styrofoam doesn't keep the lemonade cold, the bottle absorbs the heat.

• Heat will transfer from the air outside into the cooler. The transfer is slowed down by little pockets of air in the styrofoam which keeps the lemonade cool for a longer period of time.

• Heat is completely blocked from entering the cooler keeping the lemonade cold.

• The heat that builds up inside the cooler will move through the styrofoam and exit keeping the lemonade cold.

• 0.05 km/hr

• 0.05 km/hr North

• 20 km/hr North

A major league baseball player throws a baseball that has a mass of 0.145 kg at an acceleration of 42.47m/s2. The distance from pitching mound to home plate is 18.44m How much work is being done as the baseball travels to the batter?

Power (W) = Work (J) / Time (s)  

Work (J) = Force (N) x Distance (m) 

Force (N) = Mass (kg) x Acceleration (m/s2)

• 113.556J

• 6.16N

• 2.99J

• 113,556.286J
