Specific Heat and Heat Capacity Worksheet. 1. The temperature of 335 g of water changed from 24.5oC to 26.4oC. How much heat did this sample absorb? c for water = 4.18 J/goC (ans. 2.66 kJ) 2. How much heat in kilojoules has to be removed from 225g of water to lower its temperature from 25.0oC to 10.0oC? (ans. –14.1 kJ) 3.
The symbol c stands for specific heat, and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00 ºC. The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ ⋅ K) or J/(kg ⋅ ⋅ °C °C).
Specific Heat Worksheet. DIRECTIONS: Use q = (m)(ΔT)(Cp) to solve the following problems. Show all work and units. 1. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. Calculate the specific heat capacity of iron. 2.
Define heat capacity and specific heat capacity and differentiate between the two terms ; Deduce which substance will have greatest temperature changed based on specific heat capacities ; Calculate unknown variables based on known variables using the specific heat equation
Worksheet- Introduction to Specific Heat Capacities. Heating substances in the sun: The following table shows the temperature after 10.0 g of 4 different substances have been in direct sunlight for up to 60 minutes. Step 1: Create a line graph for each substance on graph below. Label the substances. Step 2: Answer questions. 1.
Specific Heat Capacity. We know that when we heat a substance the temperature will increase. The equation that links heat (energy) and temperature is: Q mc T. is the specific heat capacity which is the energy required to raise the temperature of 1 kg of a substance by 1 degree.
