A substance with a high specific heat:

Requires a lot of energy to become hot.

Does not requires a lot of energy to become hot.

The tendency of energy to spread out

The tendency of objects to warm up

The tendency of energy to make heat

The tendency of objects to do work

Negative because it is endothermic

Positive because it is exothermic

Positive because it is endothermic

When ammonium nitrate dissolves in water, the solution gets cold. Which is true?

Reaction is ENDOTHERMIC with positive ΔH

Reaction is ENDOTHERMIC with -ΔH

Reaction is EXOTHERMIC with a -ΔH

Reaction is EXOTHERMIC with +ΔH

A reaction has a positive ΔH and a positive ΔS. Which of the following is true?

It will be spontaneous at high temperatures.

It will be spontaneous at all temperatures.

It will be nonspontaneous at all temperatures.

It will be spontaneous at low temperatures.

A 5.00 gram sample of a metal at 85.0 °C comes in contact with 100.0 grams of water at 25.0 °C. What is the direction of the heat flow and why?

Metal to water, since heat flows from high temp. to low temp.

Metal to water, since heat flows from low mass to high mass

Water to metal, since heat flows from high mass to low mass

Water to metal, since heat flows from low temp. to high temp.

Thermodynamically favorable reactions...

occur without the addition of work

occur only with the addition of work

Which of the following possesses the greatest amount of entropy?

2 mol of Ar(g) at 0.5 atm and 400 K

1 mol of Ar(g) at 0.5 atm and 298 K

1 mol of Ar(g) at 0.5 atm and 400 K

2 mol of Ar(g) at 1 atm and 400 K

The reaction with the largest increase in entropy is...

CH 4 (l) + 2O 2 (g) → CO 2 (g) + 2H 2 O(g)

CH 4 (g) + 2O 2 (g) → CO 2 (g) + 2H 2 O(g)

CH 4 (l) + 2O 2 (g) → CO 2 (g) + 2H 2 O(l)

CH 4 (g) + 2O 2 (g) → CO 2 (g) + 2H 2 O(l)

For a particular chemical reaction ΔH = 5.5 kJ and ΔS = -25 J/K Under what temperature conditions is the reaction thermodynamically favored?

The reaction is not spontaneous at any temperatures.

The reaction is spontaneous at all temperatures.
