Answer:

The volume doubles

Explanation:

As per the Boyle's law for ideal gases if the gas sample temperature is kept constant, the sample volume varies inversely with the changing pressure. This declaration means the volume will decrease if the pressure increases. The volume will increase if the pressure drops. This regulation can be described like an equation which relates the initial (V1) volume and the initial (P1) pressure to the final (V2) volume and pressure (P2). At a constant heat.

⇒P1V1 = P2V2

Given P2 = P1/2

⇒ V1 = V2/2

V2 = 2V1

The volume doubles

miss Akunina [59]

The question is incomplete. The complete question is :

A spherical piece of candy is suspended in flowing water. The candy has a density of 1950 kg/m3 and has a 1.0 cm diameter. The water velocity is 1.0 m/s, the water density is assumed to be 1000.0 kg/m3, and the water viscosity is 1.0x10-3 kg/m/s. The diffusion coefficient of the candy solute in water is 2.0x10-9 m2/s, and the solubility of the candy solute in water is 2.0 kg/m3. Calculate the mass transfer coefficient (m/s) and the dissolution rate (kg/s).

Solution :

From flow over sphere, the mass transfer equation can be written as :

$Sh = 2 + 0.6 Re^{1/2} Sc^{1/3}$

where, Sherood number, $Sh = \frac{K_L d}{D_{eff}}$

            Reynolds number, $Re=\frac{Vd\rho}{\mu}$

            Schmid number, $Sc= \frac{\mu}{\rho D_{eff}}$

So,

$\frac{K_L d}{D_{eff}}=2+0.6 \left( \frac{V d \rho}{\mu} \right)^{1/2} \ \left( \frac{\mu}{\rho D_{eff}} \right)^{1/3}$

Diameter, d = 1 cm = $1 \times 10^{-2}$ m

                 V = 1 m/s

                 $\rho = 1000 \ kg/m^3$

                 $\mu = 10^{-3} \ kg/m/s$

                 $D_{eff} = 2 \times 10^{-9} \ m^2/s$

$\frac{K_L \times 10^{-2}}{2 \times 10^{-9}}=2+0.6 \left( \frac{1 \times 10^{-2} \times 10^3}{10^{-3}} \right)^{1/2} \ \left( \frac{10^{-3}}{10^3 \times 2 \times 10^{-9}} \right)^{1/3}$

$K_L \times 5 \times 10^6=478.22$

$K_L=9.5644 \times 10^{-5}$ m/s

So the mass transfer coefficient is 9.5644 $\times 10^{-5}$ m/s. It is given solubility,

$\Delta C = 2 \ kg/m^3$

$N = Md^2 \times \Delta C \times K_L$

$N= M \times (10^{-2})^2 \times 2 \times 9.5644 \times 10^{-5}$

$N= 6 \times 10^{-8}$ kg/s (dissolution rate)

ASAP!!! A cell phone charger supplies 2.0A of current to your phone. you plug in your phone overnight (8 hours). how much charge
Ksivusya [100]

current = charges / times (sec)

if a current of 2A flows for 8 hours(28800sec), then 2 * 28800 = 57600 coulombs of electrical charge move through the phone
