There is 50.0 mL of a gas at a temperature of 5°C. Its pressure is 760 mm Hg. What temperature is needed
tatuchka [14]

Answer:

41°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.

n is held constant, so:

P₁V₁ / T₁ = P₂V₂ / T₂

Given:

P₁ = 760 mmHg

V₁ = 50.0 mL

T₁ = 5°C = 278 K

P₂ = 780 mmHg

V₂ = 55 mL

Find: T₂

(760 mmHg) (50.0 mL) / (278 K) = (780 mmHg) (55 mL) / T

T = 314 K

T = 41°C

When light passes into a lower index medium it will be deviated away from the normal. True or false
V125BC [204]

Answer:

\huge\underline\color{purple}{Answer ☘}

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density).

<h3><em>when </em><em>a </em><em>light </em><em>ray </em><em>goes </em><em>from </em><em>a </em><em>medium </em><em>with </em><em>higher </em><em>refractive </em><em>index </em><em>to </em><em>a </em><em>medium </em><em>with </em><em>lower </em><em>refractive </em><em>index.</em><em>.</em><em> </em><em>it </em><em>gets </em><em>deviated </em><em>from </em><em>the </em><em>normal.</em></h3>

<h2><em>hence.</em><em>.</em><em>.</em><em> </em><em>the </em><em>statement</em><em> </em><em>is </em><em>true.</em><em>.</em><em>.</em></h2>

An object accelerates at 5 m/s2, over a 3 second time period to a final velocity of 20 m/s. What is the initial velocity?
cricket20 [7]
Using kinematic equation, v =u +at, u= v-at = 20- 3x5 = 5m/s. Initial velocity = 5 m/s
