Well most gases are lighter then metals:D
Thank you! same for u my friend! have an amazing life! :)
INFORMATION:
Is given that:
- if you have a block of plastic and a block of copper that are the same mass and are placed in the sun for 10 minutes.
And after the 10 minutes copper has a higher temperature.
We must determine the reason.
STEP BY STEP EXPLANATION:
To determine it, we need to know the concept of specific heat
If the block of copper has a higher temperature after 10 minutes, that means copper needs less heat to raise its temperature.
So, plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly.
ANSWER:
The explanation for the copper having a higher temperature after 10 minutes in the sun, is that plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly. Since the copper has a lower specific heat, it will be heat quickly.
What is the percent composition by mass of oxygen in magnesium oxide, MgO?
Answer: 39.7 percent
Potential energy
Reason why: because the quarterbacks arm has the potential to throw a ball but since it is not throwing the ball, the energy is being held... this holding of energy is called potential energy
