Answer questions true or false1. The SI tempreature unit is Celsius.2. A Kelvin is the same temperature interval as a degree Celsius.3. Because 0.00C os eqia; tp 273.15K, individual temperatures have different numerical values o n the two scales.4. A temperature difference taken between two objets has a different numerical value in kelvins and in degrees Celsius.5.Heat, like other forms of energy, is measured in kilocalories.6. Kelvin temperatue = Celsius temperature = 273.157. Molar entropies are always negative, except at 0.0K,where they are generally zero.8. The entropy of a substance increases with temperature.9. Solids have greater molar entropies than liquids.10. Gases have the most freedom to move, so their molar entropies are the greatest.11. At absolute zero, no disorder means no entropy.Practice problems:12. Calculate the amount of heat needed to raise the temperature of 180.0 g of water from 10.0C to 40.0C. The molar heat capacity for water is 75.3 J/K Mol.13. How many joules would be required to change the temperatue of 250.0g of aluminum from 15.0C to 75.0C? The molar heat capacity of aluminum is 24.2 J/K MOL14. How much heat is required to raise the temperature of 68.0 g of tin from 25.0 C to 80.0C? The molar heat capacity of tin is 11.1 J/K Mol.

Um, this is homework help. Not plagarism and slacker Deluxe lol. I already see several of these i can answer, but you're gonna have to do these on your own. I mean, just think. For number 1, you know that Fahrenheit is the US customary system. THerefore celcius must be SI.or trueFor number 11, entropy is a measure of disorder. If something is measured at absolute zero, then no particles are moving at all whatsoever. If nothing is moving randomly, then there is no disorder to measure. Therefore, there is no entropy. Just scope out your book. It should have all your answers.
