Answer:

4.7 × 10⁴ J

Explanation:

Step 1: Given data

  • Mass of water (m): 150 g
  • Initial temperature: 25 °C
  • Final temperature: 100 °C
  • Specific heat capacity of water (c): 4.184 J/g.°C

Step 2: Calculate the temperature change (ΔT)

ΔT = 100 °C - 25 °C = 75 °C

Step 3: Calculate the heat required (Q) to raise the temperature of the water

We will use the following expression.

Q = c × m × ΔT

Q = 4.184 J/g.°C × 150 g × 75 °C = 4.7 × 10⁴ J

What type of forces allow for an object to stay at rest or continue at constant velocity.
galina1969 [7]

Answer:Inertia is the property of a body to remain at rest or to remain in motion with constant velocity. Some objects have more inertia than others because the inertia of an object is equivalent to its mass.

Why is the Law of Conservation of Mass a law, rather than a theory?
Colt1911 [192]

Answer: During a chemical reaction, matter cannot be created nor destroyed, matter can change form through physical and chemical changes, but through any of these changes, matter is conserved; even though the matter may change from one form to another, the same number of atoms exists before and after the change takes place.

100!!!POINTS PLZ HELP Explain (on the molecular level) what pumping a tire with air will do to
Bas_tet [7]

Answer:

Gases are easily compressed. We can see evidence of this in Table 1 in Thermal Expansion of Solids and Liquids, where you will note that gases have the largest coefficients of volume expansion. The large coefficients mean that gases expand and contract very rapidly with temperature changes. In addition, you will note that most gases expand at the same rate, or have the same β. This raises the question as to why gases should all act in nearly the same way, when liquids and solids have widely varying expansion rates.

The answer lies in the large separation of atoms and molecules in gases, compared to their sizes, as illustrated in Figure 2. Because atoms and molecules have large separations, forces between them can be ignored, except when they collide with each other during collisions. The motion of atoms and molecules (at temperatures well above the boiling temperature) is fast, such that the gas occupies all of the accessible volume and the expansion of gases is rapid. In contrast, in liquids and solids, atoms and molecules are closer together and are quite sensitive to the forces between them.
