Below are sample questions representative of the exercises included on this worksheet and related 12.103 Specific Heat, Calorimetry, and Phase Change skill assessments:

Problem 1Difficulty: Mastery

Use the visual's two heating curves for equal-mass samples heated by identical constant-power heaters. Sample X has a melting plateau that lasts three times as long as Sample Y's plateau. What can be concluded?

ASample X has one-third the latent heat of fusion of Sample Y.

BSample X and Sample Y must have the same latent heat because mass is equal.

CSample X has a lower melting point, so its plateau is longer.

DSample X has about three times the latent heat of fusion of Sample Y.

Solution & Explanation:With equal mass and identical power, plateau time is proportional to phase-change energy mL. Since mass is equal, a three-times longer plateau means about three times the latent heat.

Problem 2Difficulty: Mastery

How much energy must be removed to change 0.300 kg of liquid water at 20°C into ice at -5°C? Use c_water = 4.18 kJ/kg·°C, L_f = 334 kJ/kg, and c_ice = 2.1 kJ/kg·°C.

A25 kJ

B100 kJ

C128 kJ

D154 kJ

Solution & Explanation:Remove energy in three steps: cool water to 0°C, 0.300×4.18×20 = 25.1 kJ; freeze, 0.300×334 = 100.2 kJ; cool ice to -5°C, 0.300×2.1×5 = 3.15 kJ. Total ≈ 128 kJ.

Problem 3Difficulty: Mastery

An ice cube melts in a warm drink. If the system is defined as the ice cube only, which sign convention is correct during melting?

Aq_ice is negative, while the drink's q is positive.

Bq_ice is positive, while the drink's q is negative.

CBoth q values are positive because both are in the cup.

DBoth q values are zero because temperature stays constant during melting.

Solution & Explanation:The ice absorbs energy to melt, so q for the ice system is positive. The drink supplies that energy and therefore has negative q if treated as a separate system.
