What energy is often called the "graveyard of kinetic energy" and why?

1 answer:

3 0

Heat is often called the "graveyard of kinetic energy". Heat due to friction. Due to friction, kinetic energy is converted to heat and not potential energy; thus, the kinetic energy is "lost" since heat cannot easily be converted back into kinetic energy.

The alveoli are surrounded by __________ carrying blood to and from the heart.

natka813 [3]

The alveoli are surrounded by tiny blood vessels, called capillaries. The alveoli and capillaries both have very thin walls, which allow the oxygen to pass from the alveolito the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

The combustion of 0.570 g of benzoic acid (ΔHcomb = 3,228 kJ/mol; MW = 122.12 g/mol) in a bomb calorimeter increased the tempera

Answer:

The temperature change from the combustion of the glucose is 6.097°C.

Explanation:

Benzoic acid;

Enthaply of combustion of benzoic acid = 3,228 kJ/mol

Mass of benzoic acid = 0.570 g

Moles of benzoic acid = $\frac{0.570 g}{122.12 g/mol}=0.004667 mol$
