Why might a rubber raft burst if it is left in the sun on a summer day?

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?

✔ it is decreased to one third of its original volume

Why might a rubber raft burst if it is left in the sun on a summer day?

✔ temperature increases, causing interior pressure to increase

Explanation:

boom baby have a sick day y'all

This is because of increase in air pressure inside the rubber raft.

Explanation:

According to Gay-Lussac's Law: 'The pressure of the gas  at constant volume is directly proportional to the temperature in Kelvins'.

(at constant Volume)

or

So, when we left rubber raft in a sun on a summer day temperature of the air inside the rubber raft increases due to which pressure of an air inside the rubber raft also increases. And by this increase in pressure rubber raft bursts.

Answer: option a.explanation.the question is incomplete. you should have shown the reaction on which x appears.any way, this question intends that you use the activity knowledge about the metals to predict which can replace x.1) then, you can approach the question by analizyng the activities of the four metallic elements shown in the choices; sr, al, sn, au.2) the activity series of the metals in the list of options, plus the hydrogen is:   sr > al > sn > h₂ > au.h₂ is included as a reference.3) from that series, you have: if the element replaced has more activity than al, only sr can replace it: these are some metals more active than aluminum but less active than sr: sr > ca > na > mg > be > al.and as the first series shows, al is more active than sn and au.then if the element fo be replaced is ca, na, mg or be, only sr is more active than al,  sn and au.from which, the answer is the option a.that has to be the answer, because any other metal would lead to an ambiguos answer.
