A piece of metal with a mass of 1.50 kilograms, specific heat of 200 J/kg · C°, and initial temperature of 100° C is dropped into an insulated jar that contains liquid with a mass of 3.00 kilograms, specific heat of l,000 J/kg · C°, and initial temperature of 0° C. The piece of metal is removed after 5 seconds, at which time its temperature is 20° C. Neglect any effects of heat transfer to the air or to the insulated jar.
What is the temperature of the liquid after the metal is removed ?
a.) 0° C
b.) 4° C
c.) 8° C
d.) 10° C
e.) 20° C
What is the average rate at which heat is transferred while the piece of metal is in the liquid ?
a.) 4,000 J/s
b.) 4,800 J/s
c.) 6,000 J/s
d.) 9,600 J/s
e.) 16,000 J/s
i have no idea what i should do
please help me
thanks
