If water with the mass of 15.0 grams is heated into water vapor in a closed system such as a closed glass jar, what is the mass of the gas after the water completely vaporizes?
a) 13.5 grams
b) 15.0 grams
c) 16.5 grams
d) the mass cannot be determined without knowing the volume.

answer:

d) the mass cannot be determined without knowing the volume.

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
