Answer:
a) 0.0483 mol
b) 232 °C
Explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
a) Given:
P = 1.20×10⁵ Pa
V = 1.00 L = 1.00×10⁻³ m³
T = 25.8 °C = 298.95 K
PV = nRT
(1.20×10⁵ Pa) (1.00×10⁻³ m³) = n (8.314 m³ Pa / mol / K) (298.95 K)
n = 0.0483 mol
b) Given:
P = 1.013×10⁵ Pa
V = 2.00 L = 2.00×10⁻³ m³
n = 0.0483 mol
PV = nRT
(1.013×10⁵ Pa) (2.00×10⁻³ m³) = (0.0483 mol) (8.314 m³ Pa / mol / K) T
T = 505.73 K
T = 232 °C
Answer:
E > A = B > C > D
Explanation:
On a semicircular curve, the magnitude of force is given by the formula as :
Here, m is the mass of the vehicle
Case A : R = 60 m v = 16 m/s
Case B : R = 15 m v = 8 m/s
Case C : R = 30 m v = 4 m/s
Case D : R = 45 m v = 4 m/s
Case E : R = 30 m v = 16 m/s
The order of the magnitude of the force of the roller-coaster track on the cart from largest to smallest is :
E > A = B > C > D

B. convection is the answer
It is round or say spherical to widen the range of photography and it is designed to focus the image as the ray are coming from infinity so !!
I am not an expert of camera but ya it is the main theme !!
