Qn 1. Why did this happen? Explain your answer in a brief manner

Answer 1

Explanation:

If we fill a jar with dried peas or beans then it swells by hypotonic solution

Hypotonic solution is the solution where the concentration ( quantity) of water in cell is lesser than the concentration of the water outside

As the peas are dried it doesn't have much water than outside , so it will swell . As the result the glass will break because the size of the swollen peas are much larger than the original dried peas . So glass jar will break
