Question

(Serway, College Physics) When an immersion heater is placed in a vessel of 30 9 whic
500 g of water, the temperature of the water increases from 25 °C to 80 °C in 6.0 minutes. specific
heat capacities of water and copper are 4200 J kg-1 K-1 and 400 J kg 1 k-1, respectively)

1. Neglecting heat losses and given that the vessel is made from copper, calculate the power of the heater.

2.When this heater (operating at the same power) is placed separately in 300 g of another liquid in a similar vessel at the same initial temperature, the temperature of the liquid reaches 62 °C in 5.0 min
What is the specific heat capacity of this unknown liquid?​
