Answer:

Explanation By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.n:

What would happen to the pressure if the volume were reduced to 0.5 l and the temperature increased to 260 ∘c?
Vsevolod [243]
<span>The ideal gas law. PV=nRT pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273) Original data Pressure 1 atmosphere Volume 1 liter Temp 25C = 298K New data Volume 0.5 liter pressure X Temp 260C = 533K P1v1T1 = P2v2T2 plug and chug. (1)(1)(293) = (x)(0.5)(533) Solve for X, which is the new pressure. </span>

Which step will decrease the pressure of a gas inside a closed cubical container? increasing the number of moles of gas decreasi
Jobisdone [24]

Answer: Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.

Explanation:

According to Gay-Lussac's Law : 'The pressure of the gas increases with increase in temperature of the gas when volume of the gas is kept constant'.

(Pressure)\propto (Temperature)

At constant volume, pressure of the gas will decrease on decreasing the temperature or vice versa.

Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.

Calculate the frequency and wavelength for a photon of light with an energy of 3.2x10-19 J.
tamaranim1 [39]

Answer:

wavelength = 6×10⁻⁷m

f = 0.5 ×10¹⁵ Hz

Explanation:

Given data:

Energy of photon = 3.2×10⁻¹⁹ J

Wavelength of photon = ?

Frequency of photon = ?

Solution:

E = h.f

f = frequency

h = planck's constant

E = energy

f = E/h

f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s

f = 0.5 ×10¹⁵ s⁻¹

s⁻¹ = Hz

f = 0.5 ×10¹⁵ Hz

Wavelength:

speed of light = wavelength × frequency

wavelength = speed of light / frequency

wavelength =  3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹  

wavelength = 6×10⁻⁷m
