Specific Heat

Specific Heat Specific Heat Capacity is the value of energy that will change the temperature of 1kg of that substance by 1oC The larger the Specific Heat, the more energy it takes to raise the object’s temperature. The more mass an object has, the more energy it will take to raise an object’s temperature. Specific Heat is a property of the material and dependent on the type of material.

Specific Heat- Conductors vs. Insulators An object with a high specific heat is an INSULATOR of heat. An object with a low specific heat is a CONDUCTOR of heat. Question: You step one foot in the sand and one foot in the grass on a hot summer day? Which feels hotter? Which has the higher temperature? Which conducts heat better? Which has a higher specific heat?

Specific Heat Capacity Q = mcpΔT Q: Heat (J) m: Mass (kg) cp: Specific Heat Capacity (J/kg °C) ΔT: Change in Temperature (°C)

Specific Heat Capacity is measured with a calorimeter

Calorimeter Energy Absorbed = Energy Released Qin = -Qout mcΔT = -mcΔT

Practice Problem #1 8340 J of heat is absorbed by 505g of water in a pot on a stove. If the initial temperature of the water was 44.3 °C, what is the final temperature of the water?

Practice Problem #2 Mr. T likes to heat up his gold chains to a toasty 40.0 °C before putting them on each day by bringing water to a boil, and then adding his gold chains and the water to a bucket. If his gold chains have a mass of 13.4 kg and start at room temperature (23.5 °C), how much boiled water must he place in the bucket with the gold chains? (ignore energy transferred to the air or the bucket)
