Specific Heat Capacity Flashcards
What is the Specific heat capacity of a substance
The amount of energy required to raise the temperature of 1kg of the substance by 1’C
What is the first step
Yo place a beaker on a balance scale and press zero
What do you do with the oil
You place it in the beaker and record the mass of the oil
What do you place in the oil
You place an immersion heater and a thermometer
What do you after you place the thermometer in
You read the temperature of the oil
What do you wrap the beaker in
You wrap it in insulation foam
What does a joulemeter do
It tells us how many joules of electrical energy pass into the emersion heater
How long do you have to leave the setup for
Around thirty minutes
What are the final readings
How many joules went through the joulemeter and the final temperature
What is the equation for specific heat capacity
Change in thermal energy = mass(kg) x specific heat capacity(J/kg ‘C) x temperature change (‘C)
How do you rearange the equation for specific heat capacity
Specific heat capacity(J/kg ‘C) = change in thermal energy(J) /(mass(kg) x temperature change(‘C))
Sources of inaccuracy
Thermal energy passing out of the beaker into the air. Not all thermal energy passing into the oil. Incorrect reading of thermometer. Thermal energy not being spread through the oil.
