Joanna adds 12,000 J of heat to a 10 kg
sample of concrete which had an initial
temperature of 15°C. What was the final
temperature of the concrete after Joanna
added the thermal energy?
a) 1.4°C
b) 13.6°C
c) 16.4°C
d) 15°C

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
