in times past on a cold winter night it was common to bring a hot object to bed with you which would keep you warmer through the cold night an 10gk jug of hot water at the same temperature

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

a electronegativity decreases beacuse the size of nucleus is bigger.
