At 25 °C, a bottle contains 2.00 L of water in its liquid state. What is the volume of the water after it freezes (at 0 °C)? The

densities of liquid water and ice are 0.997 g/mL and 0.917 g/mL, respectively.

Answer:

  • 2.175 L

Explanation:

temperature (T) = 25 degrees

volume of water (v) = 2 L = 2000 mL

density of water = 0.997 g/mL

density of ice = 0.917 g/mL

we can get the mass of the water and the use it to get the volume when it freezes to ice, this is because the mass remains the same irrespective of the change of state.

  • mass of water = volume x density  = 2000 x 0.997 = 1994 g
  • volume of ice = mass/density = 1994 / 0.917 = 2174.5 mL = 2.175 L

Light strikes a 5.0-cm thick sheet of glass at an angle of incidence in air of 50°. The sheet has parallel faces and the glass h
xxMikexx [17]

Answer:

30.81°

Explanation:

θ₁ = angle of incidence = 50°

θ₂ = Angle of refraction

n₂ = Refractive index of glass = 1.5

n₁ = Refractive index of air = 1.0003

From Snell's Law

Using Snell's law as:

n_1\times {sin\theta_1}={n_2}\times{sin\theta_2}

1.0003\times {sin50}={1.50}\times{sin\theta_2}

Angle of refraction= sin⁻¹ 0.5122 = 30.81°.

The Earth's magnetic field is approximately 0.5 Gauss. What is the magnetic energy density of this field
ser-zykov [4K]

Answer:

The  magnetic energy density  is  E_B  =  9.95 *10^{-4} \  J/m^3

Explanation:

From the question we are told that  

    The  earths magnetic field is  B  =  0.5 \  Gauss

Now

          1 \ Gauss  \to  1 *10^{-4} \ T

=>        0.5  \ Gauss  \to  x T

So  

          x =  \frac{0.5 *  1*10^{-4}}{1}

          x = B= 5.0 *10^{-5} \  T

Generally the magnetic energy density is  mathematically represented as

        E_B  =  \frac{B^2}{ 2 *  \mu_o  }

  Here \mu_o is the  permeability of  free space with a constant value

          \mu_o  =  4\pi * 10^{-7} N/A^2

substituting values for equation above  

       E_B  =  \frac{(5*10^{-5})^2}{ 2 *   4\pi * 10^{-7}  }

       E_B  =  9.95 *10^{-4} \  J/m^3
