1. un gas está encerrado en un cilindro ajustado con un pistón ligero sin fricción y se mantiene a presión atmosférica. cuando se agregan 1250 kcal de calor al gas, se observa que el volumen aumenta lentamente de 12.0 a 18.2 m3. calcule a) el trabajo realizado por el gas y b) el cambio en energía interna del gas.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
