Answer:
Has potential energy
Explanation:
A pendulum tend to have maximum potential energy at maximum displacement....so as it moves from the max displacement to the other side...the potential energy is converted to kinetic energy...which is maximum at the lowest position...in which the kinetic energy is converted back to potential energy as the pendulum approaches the top again
Answer:
n = 0.3 mol
Explanation:
Given data:
Volume of gas = 8.0 L
Temperature of gas = 45 °C (45+273 = 318 K)
Pressure of gas = 0.966 atm
Moles of gas present = ?
Ideal gas constant = R = 0.021 atm.L/mol.K
Solution:
Formula:
PV = nRT
P = Pressure
V = volume
n = number of moles
R = ideal gas constant
T = temperature
Now we will put the values:
0.966 atm × 8 L = n × 0.0821 atm.L/mol.K × 318 K
7.728 atm.L = n × 26.12 atm.L/mol
7.728 atm.L / 26.12 atm.L/mol = n
n = 0.3 mol
1kg is 1,000 grams plus .5 is 1.5 kg
