When doing numerical calculations involving temperature, youneed to pay particular attention to the temperature scale you areusing. in general, you should use the kelvin scale (for whicht=0 represents absolute zero) in such calculations. this isbecause the standard thermodynamic equations (i. e., the ideal gaslaw and the formula for energy of a gas in terms of temperature)assume that zero degrees represents absolute zero. if you are given temperatures measured in units other , convert them to kelvins before plugging them into theseequations. (you may then want to convert back into the initialtemperature unit to give your answer.)part a) the average kinetic energy of the molecules of anideal gas at 10 ^\circ {\rm c} has the value k_10. at what temperature t_1 (in degrees celsius) will the average kinetic energy ofthe same gas be twice this value, 2k_{10}? express the temperature to thenearest integer. part b) the molecules in an ideal gas at10 ^\circ {\rm c} have a root-mean-square (rms) speed v_rms. at what temperature t_2 (in degrees celsius) will the molecules have twice therms speed, 2v_{\rm rms} ? express the temperature to thenearest integer.

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3

Fill in the blanks with the numbers is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
