Approximately
.
Explanation:
Look up the specific heat of gaseous neon:
.
Calculate the required temperature change:
.
Let
denote the mass of a sample of specific heat
. Energy required to raise the temperature of this sample by
:
.
For the neon gas in this question:
Calculate the energy associated with this temperature change:
.
The correct answer is 1 to the 3rd power
ANSWER: Increase
why? Because the number of C atoms in homologous series increases gradually.
Given mass of tungsten, W = 415 g
Molar mass of tungsten, W = 183.85 g/mol
Calculating moles of tungsten from mass and molar mass:

C. Include changes that alter the identity of a substance.
