     When you see homework covering the kitchen table and toys are piling up around the sofa, you

probably wish there was a bit more space. You are not alone. Nearly a third of parents say they feel

squeezed into their homes but cannot afford to move to a bigger property,a report reveals today.

     Twenty-nine percent say 'their property is too small to fit the size of their family'-rising to 40 percent

for those 34 and under. One in four children is 'forced to share'a bedroom, according to the

Finda-Property. Com website. Property analyst Samantha Baden said:"Afford-ability remains a key issue

for families, with the average cost of a three-bedroom home around £ 193,000."Very few can afford

to buy - or to rent - a property of the size they want and in the area they desire to live in, according to

Miss Baden.

     A recent report, from investment firm LV, also found that many 'space-starved parents'are pushed

into a two-bedroom home which was perfect when they were a young couple, but has no space for three

or so children. Grown-up children who cannot afford to leave home are also adding to the problem facing

families in Britain's 'big squeeze'.

     For a home to be the correct size, which means it is not overcrowded, parents must have their own

bedroom. Children under ten can share, as well as same-sex children between ten and 20.Any-one over

21 also needs their own room.

     The report comes as official figures, published yesterday by the Land Registry, revealing house prices

are falling sharply in every region except London. The worst - hit area is the North East, where average

house prices have fallen to below £ l00,000 for the first time in seven years. However, they remain

unaffordable for millions.

H2O(g)= H2O(l) △H1 =-Q1kJ·mol-1(Q1>0)

C2H5OH(g)= C2H5OH(l) △H2 =-Q2kJ·mol-1(Q2>0)

C2H5OH(g)+3O2(g)= 2CO2(g)+3H2O(g) △H3 =-Q3kJ·mol-1(Q3>0)
