Melting freezing and boiling are molecular changes
An image that can be projected on a screen is a real image. A real image can be larger than the original object.
good luck
The answer is D. Chemical Energy
Answer:
18 L
Explanation:
Use ideal gas law:
PV = nRT
Find initial number of moles, but first convert to units that match the gas constant units.
(200,000 Pa) (0.025 m³) = n (8.314 Pa m³ / mol / K) (25 + 273.15 K)
n = 2.017 mol
At the new pressure and temperature:
(250,000 Pa) V = (2.017 mol) (8.314 Pa m³ / mol / K) (0 + 273.15 K)
V = 0.018 m³
V = 18 L
Answer:
the volume that has 1.0m^2 of water from the surface of the lake is 4.3
Explanation:
The computation of the volume is as follows;
The Bulk modulus is
= K = 2.3 × 10^9 Pa
K = - V dP ÷ dV
dV = - V dP ÷ K
dV = - (1 × 101.3 × 1000) ÷ 2.3 × 10^9
= - 4.3 × 10^-3 m^3
So the volume that has 1.0m^2 of water from the surface of the lake is 4.3
Hence the same is relevant and considered
