(PLS QUICKLY) A system has both thermal energy and chemical potential energy boosrding to the law of conservation of energy, which statement describes the total energy of this system? O A. It will decrease orer time as chemical potential energy is transformed into thermal energy O B. It will increase as thermal energy is created from chemical potential energy C. It will remain constant because the total amount of thermal energy plus chemical potential energy stays the same D. It will decrease as thermal energy is transferred out of the system.​

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.
