1. How much thermal energy is required to raise the temperature of 6.0 mL of water
from 25 °C to 75 °C in a calorimeter or other closed system? spy fans: 1.3 kJ
2. Aqueous ethylene glycol is commonly used in car radiators as an antifreeze and
coolant. A 50 % ethylene glycol solution in a radiator has a specific heat capacity,
C, of 3.5 J/g-C), a 4.0 kg quantity of ethylene glycol absorbs 250 kJ of thermal
energy, what was the temperature change, AT, of the solution? Assume the radiator
is a dosed system. sz fans: 18 °C]
