At a fabrication plant, a hot metal forging has a mass of 67.2 kg and a specific heat capacity of 438 j/(kg c°). to harden it, the forging is quenched by immersion in 786 kg of oil that has a temperature of 37.1 °c and a specific heat capacity of 2950 j/(kg c°). the final temperature of the oil and forging at thermal equilibrium is 58.3 °c.
assuming that heat flows only between the forging and the oil, determine the initial temperature in degrees celsius of the forging.

Does anyone know how to solve this problem? i really need . i made an attempt but i just cant get it. a metal rod is 25.000 cm long at 25.0 degrees celsius. when heated to 102.0 degrees celsius, it is 25.054 cm long. what is the coefficient of linear expansion for this metal.

Urgent pls a. coal consumption levels off and remains flat. b. petroleum, natural gas, and renewables show an increase in consumption c. more nonrenewable resources continued to be consumed than renewable. d. there is little projected increase in nuclear energy use. e. carbon dioxide emissions are projected to decline as we approach 2040. global energy consumption is defined as the total energy used by an individual or organizations from around the world. use the graph above to analyze the projected energy consumption from now until 2040. which statements in the prompt apply? a) a, b, d b) b, c, d c) a, c, d d) a, b, c, d

First to answer will be the brainliest i need the answer asap
