A gas delivers 874 J of heat and then has 159 J of work done upon it. The change in internal energy of the gas is
Nesterboy [21]

The change in internal energy of this gas sample is equal to: c. 715 J.

<u>Given the following data:</u>

  • Quantity of heat = 874 J.
  • Work done = 159 J.

<h3>What is the First Law of Thermodynamics?</h3>

Mathematically, the the First Law of Thermodynamics is given by this formula:

\Delta H = Q-W

Where;

  • \Delta H is the change in internal energy.
  • Q is the quantity of heat.
  • W is the work done.

Substituting the parameters into the formula, we have;

\Delta H =874-159\\\\\Delta H = 715

Change in internal energy (ΔH) = 715 Joules.

antoniya [11.8K]

Answer: b. Remains of formerly living things buried by sediments in regions with little oxygen.

Explanation:

Fossil fuels are underground geological fuel deposits which are formed from the decaying of organic materials (animals and plants) over hundreds of millions of years in the earth's crust, which furthur processed into coal, crude oil, heavy oils or natural gas by exposure to pressure and heat

Fossil fules are present only in sedimentary rocks under litte oxygen the provide temperatures and pressures that do not kill fossil remains, unlike most igneousand metamorphic rocks.

Hence, the correct option is b.
