A small immersion heater is rated at 380 W. Estimate how long it will take to heat a cup of soup (assume this is 295 mL of water) from 18.2oC to 48.4oC.© BrainMass Inc. brainmass.com December 24, 2021, 5:37 pm ad1c9bdddf
Hello and thank you for posting your question to Brainmass
The power of the heater in Watts (P), indicates how many Joules the heater produces in one second.
Thus the total energy the heater produces in time t is:
W = Pt
The heat flowing into the water Q, causes ...
This solution estimates how long it will take to heat a cup of soup from 18.2oC to 48.4oC.
