What is a collision and how does mass affects a collision​

:)

Explanation:

A collision is the impact of 2 objects forcefully coming together in physical contact. So for example, a gold club and gold ball. The club comes in direct contact with the gold ball causing a collision. If the golf club had double the mass of the golf ball, it would result in the gold ball having twice the momentum even if they were moving at both the same speed and direction. Hope this helps explain a bit better!

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

put the answers   and i could answer.
