A 10 Watt electric heater is used to heat a container filled with 0.5 kg of water. It is found that the temperature of water and the container rises by 3, K in 15 minutes. The container is then emptied, dried and filled with 2 kg of oil. The same heater now raises the temperature of container-oil system by 2''K in 20 minutes. Assuming that there is no heat loss in the process and the specific heat of water as `"4200 J . kg"^(-1).K^(-1)`, the specific heat of oil in the same unit is equal to
