spoon. Isabel finds that her spoon is hot to the touch while Tricia\u2019s is still cool.<\/p>\n

a) Describe how the heat travelled through the metal spoon. Explain your answer in terms of the<\/p>\n

particles of the metal.<\/p>\n

b) Why did Tricia\u2019s spoon stay cool?<\/p>\n

c) Copy the tables below into your jotter and complete it to show the uses of conductors and insulators in the home.<\/p>\n
