How could you determine that a liquid has transferred thermal energy to the air?
The temperature of the air would increase.
By increasing the motion of the air particles due to an increase in thermal energy, the average kinetic energy of the particles increases, ultimately leading to a rise in temperature.

You can observe temperature changes in the liquid and surrounding air, use a thermometer to measure temperature variations, or employ infrared thermography to visualize heat transfer.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A sample of metal with a specific heat of .502 J/g°c is heated to 100.0°C and then placed a 50.0 g sample of water at 20.0°C. The final temperature of the system is 76.2°C. What is the mass of the metal used in process?
- Why is jet fuel used as an aviation fuel in preference to dihydrogen gas? Does it make sense in terms of the energy yield?
- If the net #DeltaH# is zero, is the reaction an endothermic or exothermic process?
- Does anyone know the value for the standard enthalpy of formation of liquid nitric acid HNO3 ?
