Exactly one mole of an ideal gas with a cv, m of 3.5 r serves as the working substance during a carnot cycle. the high temperature is 800.0 k and the low temperature is 373.15 k. during the isothermal expansion, the work done by the gas is 4.184 × 10 calculate (a) the thermodynamic efficiency (as a percentage) of the carnot cycle. (b) the amount of heat that is absorbed from the hot source i. e. qh) (c) the amount of heat that is released to the cold sink (i. e. qc) (d) the amount of work done by the gas in each cycle.

Write a balanced equation showing the formation of copper (ii) nitrite from its elements

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
