Answer:
3.3atm is the new pressure of the container
Explanation:
In the car, the temperature of the container increases from 25°C =298K to 55°C = 328K. To solve this question we must use the Boyle's law that state that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:
P1T2 = P2T1
<em>Where P is pressure and T absolute temperature of 1, initial state of the gas and 2, final state.</em>
<em />
Replacing:
P1 = 3atm
T2 = 328K
P2 = ?
T1 = 298K
3atm*328K = P2*298K
P2 = 3.3atm is the new pressure of the container

Answer:
A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy), with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.
