The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.
The question is based on the Thermodynamic principle of Specific Heat Capacity. Now, Specific Heat Capacity refers to the amount of heat needed per unit mass t raise the temperature by one degree Celsius
The formula that can be used to find the answer is the following:
Q = C · m · ΔT ( where Q is the heat added/required; C is the specific heat capacity [4.186 joule/gram °C]; ΔT is the change in temperature)
Based on the question, what needs to be found is Q, and what is known is that C = 4.186 J/g °C; m = 15 g; ΔT = 10 °C
so, Q = C · m · ΔT
Q = (4.186 J/g °C) (15 g) (10 °C)
Q = 627.9 J
Thus, the number of <span>joules required to raise the temperature of 15.0 grams of water by 10 degrees Celsius is 627.9 J</span>
Answer:
movement of charged particles through the wire .
Explanation:
When electricity is passed through the wire of electromagnet , moving electrons of the wire produces magnetic field . This magnetic field in increased due to high permeability of soft iron of the electromagnet . It is this magnetic field which creates magnetic force .
Answer:
An important example of chemical potential energy is the energy stored in the food that you eat. Inside your body, this food is distributed around your body and is reacted in your cells to release the energy stored in the chemical bonds.
