Does the entropy of the space into which a star radiates (which has a temperature of about 3 k) increase or decrease? what does this do to the entropy of the universe?
Charlotte AaronTo the best of our current knowledge, Universal entropy is ALWAYS increasing.
The entropy of the star matter increases when a star emits radiation; element formation, for example, may cause a localized decrease in entropy in the radiation-affected region, but overall system entropy continues to rise.

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.

- In the morning, a concrete statue of specific heat = 600 j/(kg k) has a temperature of 15°c. during the day, it sits in the sun and warms up to 40°c, gaining 90,000 j of thermal energy. what is its mass?
- A #4 L# container holds #19 # mol and #20 # mol of gasses A and B, respectively. Groups of four of molecules of gas B bind to three molecule of gas A and the reaction changes the temperature from #210^oK# to #120^oK#. How much does the pressure change?
- An #8 L# container holds #8 # mol and #9 # mol of gasses A and B, respectively. Every two molecules of gas B bind to one molecule of gas A and the reaction raises the temperature from #370^oK# to #425 ^oK#. How much does the pressure change by?
- A #7 L# container holds #7 # mol and #18 # mol of gasses A and B, respectively. Every three of molecules of gas B bind to one molecule of gas A and the reaction changes the temperature from #320^oK# to #240 ^oK#. By how much does the pressure change?
