A heat pump has a coefficient of performance of 7.05. If the heat pump absorbs 20 cal of heat from the cold outdoors in each cycle, find the heat expelled to the warm indoors. Answer in units of cal.

I believe COP (heating mode) : 7.05 and COP = Qh/W

Qc = 20 cal

so I have to find Qh= ? cal

I dont know an equation to put all this together?

Please help, thank you.
