A 35.5-g glass thermometer reads 23.1 °C before it is placed in 131 mL of water. When the water and thermometer come to equilibrium, the thermometer reads 42.3 °C. Ignore the mass of fluid inside the glass thermometer. The value of specific heat for water is 4186 J/kg. C°, and for glass is 840 J/kg - C°. ▾ Part A What was the original temperature of the water? Express your answer using three significant figures. VE ΑΣΦ ? T = Submit Request Answer °C
When a 310-g piece of iron at 180 °C is placed in a 95-g aluminum calorimeter cup containing 250 g of liquid at 10°C, the final temperature is observed to be 36 °C. The value of specific heat for iron is 450 J/kg. C°, and for aluminum is 900 J/kg Co. ▾ Part A Determine the specific heat of the liquid. Express your answer using two significant figures. VG| ΑΣΦ ?
