Question 1. <\/span><\/h4>\n

The table below shows the ways in which heat is lost from a house.\"Heat4\"<\/a><\/p>\n

a)What was the percentage heat loss for the floor?
\nb) Use the table of results, including your value for heat loss from the floor, to draw a graph that shows how heat is lost from the home.<\/p>\n

Question 8. <\/span><\/h4>\n

A man fell overboard from a yacht. His friend rescued him from the sea 20 minutes later. The sea temperature was 8 C and the air temperature was only 4 C, yet the man in the sea developed hypothermia, but the man in the yacht did not, despite them both being dressed the same.
