I) The temperature at which nitrogen (dinitrogen, N2, also called "liquid nitrogen" or LN2) boils is a chilly - 195.8 °C. Convert this to Kelvin. 2) The temperature at which nitrogen (dinitrogen, N2, also called “liquid nitrogen" or LN2) boils is a chilly - 195.8 °C. Convert this to degrees Fahrenheit. 3) Kelvin is an absolute scale, so exactly zero Kelvin means exactly zero thermal energy (absolute zero). Fahrenheit, while more familiar, has its zero defined relative to some arbitrary phenomenon. Calculate what absolute zero would be measured as in the Fahrenheit scale units. Hint/Aside: We've all got that friend who's prone to exaggeration; this winter when yours says ifs -1000 outside, you can tell him that's impossible. Don't actually do this though - it's snotty and there are other temperature units where -1000 is possible. 4) A chunk of gold is changed from initial temperature 400.0 °C to a final temperature of 200.0K. What temperature change did this sample undergo? Report the answer as a change in units of degrees Celsius. 5) A chunk of gold is changed from initial temperature 400.0°C to a final temperature of 200.0K. What temperature change did this sample undergo? Report the answer as a change in Kelvin units.

Can you please do all of them Ill thump up if you do. Thank you

For all calculations, unless explicitily directed otherwise, report in standard units for the requested quantity but do not include the unit in the answer field. Report more digits than are significant, and if you choose to report in scientific notation, remember Bb understands the number 1.2345 x 10°as entered: 1.2345 E5 (no spaces, capital E). Negative temperatures are possible, as are negative temperature changes. There are no vectors involved to handle reporting directional information as was the case for velocity, etc. If you need to report a negative answer, include the negative sign in the answer field. 1) The temperature at which nitrogen (dinitrogen, N2, also called “liquid nitrogen" or LN2) boils is a chilly - 195.8 °C. Convert this to Kelvin. 2) The temperature at which nitrogen (dinitrogen, N2, also called “liquid nitrogen" or LN2) boils is a chilly – 195.8 °C. Convert this to degrees Fahrenheit. 3) Kelvin is an absolute scale, so exactly zero Kelvin means exactly zero thermal energy (absolute zero).
