Answer:

<em>The valid conclusion is:</em>

  • <u><em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em></u>

<u><em></em></u>

Explanation:

The answer choices are:

  • <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
  • <em>B. the temperature of the object is decreasing, while the temperature of the water is decreasing</em>
  • <em>C. the temperature of the object is increasing, while the temperature of the water is increasing</em>
  • <em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em>

<em />

<h2>Solution</h2>

<em />

Thermal or heat energy always flows from the hotter substances to the cooler substances.

Thus, since the arrows show that the thermal energy is flowing from the water to the object, the water is losing thermal energy and the object is gaining thermal energy.

When an object gains thermal energy, and there is not involved a change of phase, the temperature of the object increases. Thus, the temperature of the object is increasing.

On the other hand, since water is losing thermal energy, and there is not involved a change of phase, the temperature of the water decreases.

Therefore, the correct conclusion is described by the option A:

  • <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>

The muscles on the run in transform chemical potential energy into_____
LekaFEV [45]

Mechanical Energy

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

Explanation:

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle.  The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.

This process is never 100% efficient with some energy lost as heat energy.

You’ve just started a new job in the laboratory of the Food and Drug Administration. Your supervisor asks you to prepare a 1.50-
anastassius [24]

Answer:  118.5 grams

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n= moles of solute

V_s = volume of solution in ml = 500 ml

1.50=\frac{moles\times 1000}{500ml}

moles = 0.75

moles of solute =\frac{\text {given mass}}{\text {molar mass}}

0.75 =\frac{\text {given mass}}{158g/mol}

mass of KMnO_4 = 118.5 grams

Thus mass of KMnO_4 needed to prepare 500 mL of this solution iis 118.5 grams
