Sample questions from this chapter

What is heat in thermodynamics?
  1. Energy transferred because of a temperature difference ✓
  2. The total internal energy permanently contained in a body
  3. A measure of the body's degree of hotness
  4. Matter flowing from a hotter body to a colder body
Answer: A. Heat is energy exchanged between systems solely because their temperatures differ.
Why not B: Internal energy is a state property; heat names energy in transit across a boundary.
Why not C: Temperature, not heat, quantifies hotness and determines the direction of transfer.
Why not D: Heat is energy transfer and does not require matter itself to cross the boundary.
What Kelvin temperature corresponds to 27.0 °C?
  1. 246 K
  2. 273 K
  3. 300 K ✓
  4. 327 K
Answer: C. T=27.0+273.15=300.15 K, which rounds to 300 K.
Why not A: This subtracts the Celsius reading from 273 instead of adding it.
Why not B: This ignores the stated 27.0-degree rise above zero Celsius.
Why not D: This adds 300 rather than 273.15 to the Celsius reading.
A 0.100 kg ice sample at 0 °C is placed in 0.500 kg water at 40.0 °C in an insulated vessel. Take c_water=4.20×10³ J kg⁻¹ K⁻¹ and L_f=3.36×10⁵ J kg⁻¹. What is the final temperature?
  1. 20.0 °C ✓
  2. 16.0 °C
  3. 24.0 °C
  4. 0 °C
Answer: A. Energy balance 0.5c(40−T)=0.1L_f+0.1cT gives T=20.0 °C.
Why not B: This cools the original water but omits the melted ice's heat capacity above 0 °C.
Why not C: This subtracts latent heat but divides only by the original water's thermal capacity.
Why not D: The warm water can supply more than the 33.6 kJ needed to melt all the ice.
