A steam engine receives 300 kJ of heat from its environment and does 400 kJ of work. How much does the energy of the steam engine change?
Energy of system is decreased by
Form 1st law of thermodynamics
[Work is done by the steam engine. Hence i took -400 kJ]

The change in energy of the steam engine can be calculated using the First Law of Thermodynamics:
Change in energy = Heat input - Work done
Given: Heat input = 300 kJ Work done = 400 kJ
Change in energy = 300 kJ - 400 kJ Change in energy = -100 kJ
Therefore, the energy of the steam engine decreases by 100 kJ.

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 star is five times as luminous as the Sun and has a surface temperature of 98,000 K. What is its radius, compared to that of the Sun?
- A #3 L# container holds #9 # mol and #12 # mol of gasses A and B, respectively. Groups of three of molecules of gas B bind to two molecules of gas A and the reaction changes the temperature from #160# #K# to #360# #K#. How much does the pressure change?
- A #3 L# container holds #30 # mol and #15 # mol of gasses A and B, respectively. Groups of three of molecules of gas B bind to five molecules of gas A and the reaction changes the temperature from #320^oK# to #480^oK#. How much does the pressure change?
- The temperature of a block of iron, which has a specific heat of 450 j/(kg k), increases by 3 k when 2700 j of energy are added to it. what is the mass of this block of iron?
- A #5 L# container holds #5 # mol and #10 # mol of gasses A and B, respectively. Every five of molecules of gas B bind to two molecule of gas A and the reaction changes the temperature from #320^oK# to #450 ^oK#. By how much does the pressure change?
