Answer:
Use an insulated beaker full of water. The insulation reduces heat loss. Use a top pan balance to measure the mass of the empty beaker and then the beaker and water. Calculate the mass of the water by subtracting. Measure the temperature of the water before heating using a thermometer. Use a heater with an ammeter connected in series to measure the current in the heater and a voltmeter in parallel with the heater to measure the pd. Record the time the heater is on and measure the end temperature of the water. Use E = I × V × t to determine energy supplied to the Water. Use ΔE = m × c × ΔΘ to determine the specific heat capacity of the water.
