When two objects come in contact with each other, friction occurs and a
both objects change directions

b
both objects will receive a certain amount of thermal energy and heat up

c
one object will heat up while the other cools down

d
both objects immediately cool down to room temperature

b

both objects will receive a certain amount of thermal energy and heat up

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
