When karl kaveman adds chilled grog to his new granite mug, he removes 10.9 kj of energy from the mug. if it has a mass of 625 g and was at 25°c, what is its new temperature? specific heat capacity of granite = 0.79 j/(g·k)

3°C

Explanation:

We can that heat Q=m dT

Where m is the mass = specific heat capacity

dT = Temperature difference

here we have given m=625 g =.625 kg

specific heat of granite =0.79 J/(g-K) = 0.79 KJ/(kg-k)

=25°C

we have to find

we have also given Q=10.9 KJ

10.9=0.625×0.79×(25-)

25- =22

=3°C

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
