Answer:
The answer is below
Explanation:
Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:
V = kT, where V = volume and T = temperature, k = constant. Therefore:
V / T = k
Given that:
The new volume is 3.41 m³. That is it expands by 0.41 m³
Answer:
The answer is letter C, The energy of the supersaturated liquid is converted to heat as the compound crystallizes.
Explanation:
"Hand warmers" are very essential when the cold season comes. It provides warmth to the hands, especially when going outdoors. There are different kinds of hand warmers, such as the<em> "reusable hand warmer." </em>In contrast to air-activated hand warmers, the reusable hand warmers contain sodium acetate (not iron).
Sodium acetate is a "supersaturated liquid." This means that is has more substances dissolved in it. So, when this crystallizes, heat is released. Remember that crystallization is considered an "exothermic process." This means that the process releases energy (in this case, through "heat").
Thus, this explains the answer, letter C.
Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.
