One one hot summer day your mom brings you a tall glass of lemonade as your playing in the yard. You notice that the thermal energy is flowing from the lemonade to the ice cubes and cooling it down. Because we know that it always flows from Hot to Cold! When do you think the thermal energy will stop flowing?
When the lemonade freezes
When the ice melts and reaches a homeostasis
When the lemonade boils
When the lemonade is in your belly
What is this an example of?
Gravitational potential energy
Mechanical Energy
Elastic potential energy
Electrical energy
What is one benefit of using fossil fuels for energy?
They can be easily harvested and are very expensive
They are very hard to be found and are expensive
They are easily harvested and are relatively cheap
They have high start up costs, but the fuel is free
You put a piece of ice into a glass of water. The ice cube is 30 degrees Fahrenheit, and the water is 60 degrees Fahrenheit. You are an expert in thermal energy transfer, so you can make one correct assumption about what will occur.
The thermal energy will flow from the ice to the water and it will make the water 50 degrees
The thermal energy will flow from the water to the ice and it will make the water 45 degrees
The thermal energy will flow from the water to the ice and it will make the water 30 degrees
The thermal energy will flow from the ice to the water and it will make the water 45 degrees
