Answer:
A. Elastic
Explanation:
an elastic collision is one which there is no overall loss of kinetic energy
Answer:
When fossil fuels are burned, carbon- dioxide and other greenhouse gases are released which trap the Sun's heat and can lead to global warming. The over heating of the atmosphere can put ecosystems under pressure especially the tundra regions.
Answer : The final volume at STP is, 1000 L
Explanation :
According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.
or,
where,
= initial pressure = 1520 mmHg = 2 atm (1 atm = 760 mmHg)
= final pressure at STP = 1 atm
= initial volume = 500.0 L
= final volume at STP = ?
Now put all the given values in the above formula, we get:
Therefore, the final volume at STP is, 1000 L
