Frederick Pratt · Answer 1

Maple syrup will have the higher temperature.

Explanation:

Adding CaCl₂ to water and maple syrup will rise the temperature of both of them. Knowing that:

Specific heat of maple syrup = 2.01 J/g.°C.

Specific heat of water = 4.18 J/g.°C.

Which means that the energy needed to rise the temperature by 1.0 °C of 1.0 g of water (4.18 J) is twice as that needed to rise the temperature by 1.0 °C of 1.0 g of water (2.01 J). So, the temperature of maple syrup will be higher than that of water when CaCl₂ is added to both of them.
