Answer</h2>
The <u>inter or intramolecular bonding forces</u> affect the physical properties of the metals and nonmetals.
<h2>
Explanation</h2>
The bonding forces of the element in the periodic table get varied within the periods and groups. In the groups, more shells increase the shielding effects and in the periods, the repulsion among the electrons increases. These factors affect the behaviour of an atom during the process of making bonding or reactions. These are the reasons which make the most of the metals in the solid form and nonmetals in the liquid or gas forms.
Answer:
Ratio of wavelength will be 1.1982
Explanation:
We know that velocity in any medium is given by , here c is the velocity of light and n is the refractive index
We know that wavelength is given by , from the relation we can see that wavelength is inversely proportional to the refractive index
We have given refractive index of carbon disulfide = 1.632
And refractive index of ethyl alcohol = 1.362
So ratio of wavelength of ethyl alcohol and carbon disulfide =
Answer:
5.76 cm³
Explanation:
Using the equation for volume expansivity,
V = V₀ + V₀γΔθ) where V₀ = volume of cube = volume of mercury = 400 cm³, γ = cubic expansivity of mercury = 18 × 10⁻⁵ /K and Δθ temperature change = θ₂ - θ₁ where θ₁ = 0 °C and θ₂ = 80°C. So, Δθ = 80°C - 0°C = 80°C = 80 K
Now, the volume change, ΔV = V - V₀ = V₀γΔθ.
So, substituting the values of the variables into the equation, we have
ΔV = V₀γΔθ
= 400 cm³ × 18 × 10⁻⁵ /K × 80 K
= 5.76 cm³
So the mercury will overflow by 5.76 cm³.
