Answer:
We know that kinetic energy is one of the forms of internal energy, so the release of heat from an object causes a decrease in the average kinetic energy of its particles.
Answer:
B
Explanation:
The attraction is stronger when the magnet is closer so moving it away would decrease the strength.
They tend to pick at it until it is in small enough pieces to swallow. Then their gizzard (rough muscle) in their stomach acts as internal teeth.
<u>Ans: 0.225 atm</u>
<u></u>
<u>Given:</u>
Initial volume of gas, V1 = 450 ml = 0.450 L
initial pressure, P1 = 1.00 atm
Final volume, V2 = 2.00 L
<u>To determine:</u>
Final pressure, P2
<u>Explanation:</u>
Based on ideal gas equation:
PV = nRT ----(1)
where P = pressure, V = volume, n = # moles, R = gas constant, T = temp
Under constant, T and n, eq(1) can be expressed as:
PV = constant
(or) P1V1 = P2V2
P2 = P1V1/V2 = 1.00 atm * 0.450 L/2.00 L = 0.225 atm
