1. The correct answer among the choices provided is the third option. Measuring the temperature increase of water from doing work by stirring it is an experiment generally regarded as being first carried out by James Joule.
2.  Joule's experiment directly shows that heat is a form of energy. He wanted to make a different way of measuring energy.

Answer 1: The correct answer is: 'measuring the temperature increase of water from doing work stirring it'.

Answer 2: The correct answer is :'Heat is a form of energy'.

Explanation:

In his experiment he took three fluids : water, oil, mercury in an insulating container with stirrer agitated in the fluid.

He measured the amount of work done by the rotating stirrer in the fluid and the temperature rise in the fluid due to the rotation of the stirrer was also observed.

From his observation he concluded that the heat possessed by the fluid and work done on the fluid is directly linked to each other. Which he put down is simple words "heat is a form of energy"

The grains found in igneous rock:
kondor19780726 [428]
Option c. are large

Igneous rocks are crystalline  solids which are formed after the magma cools. The sizes vary greatly depending on how quickly the magma cooled. The slower the cooling, the larger the crystals in the final rock. They cooled at depth in the crust  where they were insulated by layers of rock and sediment.

Due to radiation and absorption, what is the maximum flame temperature in a fire?
ludmilkaskok [199]

The maximum flame temperature in a fire is 1500-1600K due to radiation and absorption.

<h3>What do you mean by radiation and absorption?</h3>

In physics, matter (usually electrons bound in atoms) absorbs electromagnetic radiation in order to convert the energy of a photon into the internal energy of the absorber (for example, thermal energy). Attenuation, or the steady decrease in light wave intensity as it travels through a medium, is a prominent effect. In some circumstances (optics), the medium's transparency changes by a factor that varies as a function of wave intensity, leading to saturable absorption (or nonlinear absorption), even though the absorption of waves typically does not depend on their intensity (linear absorption).
