Mercury has one of the lowest specific heats. This fact added to its liquid state at most atmospheric temperatures make it effec
UNO [17]

The specific heat of mercury is 149.4 J/(kgK)

Explanation:

When a substance is supplied with an amount of energy Q, its temperature increases according to the equation:

\Delta T=\frac{Q}{mC_s}

where

\Delta T is the increase in temperature

m is the mass of the sample

C_s is its specific heat capacity

For the sample of mercury in this problem we have

Q = 275 J

m = 0.450 kg

\Delta T = 4.09 K

Therefore, by re-arranging the equation we find the mercury's specific heat:

C_s = \frac{Q}{m\Delta T}=\frac{275}{(0.450)(4.09)}=149.4 J/(kgK)

What happens to the pressure of a gas inside a container if the temperature of the gas decreases?
My name is Ann [436]

Answer:

Pressure Increases

Explanation:

When the temperature of a gas is increased inside a container then the pressure of the gas inside the container increases.

This can be deduced by the Ideal Gas law equation:

P.V=n.R.T

where:

P = pressure of the gas

V = volume of the gas

n = no. of moles of gas

R = universal gas constant

T= temperature of the gas

So,

P\propto T hence the pressure of the gas will increase while the temperature is increased at a constant volume

Answer:

The charge flows in coulombs is

dq=1.843x10^{-5}C

Explanation:

The current magnitude of current is given by the resistance and the induced Emf as:

I=N*\frac{dF}{Rdt}

\frac{dq}{dt}=\frac{dF}{Rdt}=dq=N*\frac{dF}{R}

dq=\frac{N*\beta*A*(Cos(\alpha_f)-Cos(\alpha_i}{R}

N=1300, \beta=0.703, A=\pi*r^2=\pi*0.10^2=0.01\pi m^2, R=99.4+202=301.4Ω

\alpha_f=14.6,\alpha_i=165.4

Replacing :

dq=\frac{1300*0.703x10^{-4}*0.01\pi*(0.9667-(-0.9667))}{202+99.4}

dq=1.843x10^{-5}C
