An electrical heater warms 180g of water.its initial temperature is 35 Celsius .the heater emits 200J of heat each 1 minute.heat capacity of water is 4.18J/kg.what is the new temperature of the water after 5 minutes of heating.

I have a feeling that your title does not fit your question... :confused:

Remember the formula:



Q is the total amount of heat, in joules,
m is the mass of the substance being heated (or cooled)
c is the specific heat capacity of the substance,
theta is the change in temperature.

Can you give this problem a try now? :)
