a calorimeter consists of an aluminum cup inside of an insulated container. the cup
is weighed on a top-loading balance and is found to have a mass of 42.14 g. a
reaction is conducted in the calorimeter, raising the temperature from 20.00°c to
26.41°c. what is the change in heat, q, for the aluminum cup, in units of j?
aluminum has a specific heat of 0.903 j g-1 °c-1.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
