A4.0-kg aluminum block is originally at 10°
c. if 160 kj of heat is added to the block, what is its final temperature? the specific heat capacity of aluminum is 910 j/kg · k

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
