Module 7: L3/ L4 TEST

The temperature of a 1kg of iron increases more than 1kg of water when the same amount of thermal energy is added. This is because ___________.

• iron has a higher specific heat.
• iron has a lower specific heat.
• iron has a higher melting point.
• water is a liquid and iron is a solid.
