Rank the size of a change in temperature of one degree fahrenheit, one degree celsius, and one kelvin. in other words, if a thermometer were to show that the temperature outside increased by these amounts, which change would feel the largest? if any of the options are the same magnitude, stack them above one another. rank the sizes of one degree in each scale from largest to smallest. to rank items as equivalent, overlap them.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
