550 g of water at 105°C is poured into an 855 g aluminum container with an initial temperature of 11°C. The specific heat of alu

nexus9112 [7]

Answer:

54.22 kJ

Explanation:

In this case, we need to calculate the heat. The expression to use is:

Q = m * C * ΔT

Now, with the specific heat of water (4186 J/ kg K), we can calculate the temperature in which this occurs.

So:

Q = 0.550 * 4186 * (105 - T)

Q = 2302.3 (105 - T)

Q = 241,741.5 - 2302.3T

Now with the Aluminium:

Q = 0.855 * 900 * (T - 11)

Q = 769.5T - 8464.5

Now, with both equations, we solve for the final temperature:

769.5T - 8464.5 = 241,741.5 - 2302.3T

(2302.3 + 769.5)T = 241,741.5 + 8464.5

3071.8T = 250,206

T = 81.45 K

This is the temperature which the change occurs. Now, let's determine the amount of heat from water to Al:

Q = 241,741.5 - 2302.3(81.45)

Q = 54,219.17 J or simply 54.22 kJ.

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

An uncharged conductor has a hollow cavity inside of it. Within this cavity there is a charge of +10 µC that does not touch the

aliina [53]

Answer:

Explanation:

we have to make charge inside the conductor zero because we know that electric field inside the conductor should be zero

so, the outer surface of the conductor should contain + 10 uC of charge and the inner surface contains -10 uC

A research submarine has a 10-cm-diameter window that is 8.4 cm thick. The manufacturer says the window can withstand forces up

Dmitrij [34]

Pnet = Po + dgh

Density of saltwater = 1030 kg/m^3. 

Disregard the thickness. Assuming it's a circular window, then the area is pi(r^2). 

d = 20 cm = 0.2 m 
r = d/2 = 0.1 m 

A = pi(r^2) 
A = 3.14159265(.1^2) 
A = 0.0314159265 m^2 

p = F/A 
p = (1.1 x 10^6) / (0.0314159265) 
p = 35,014,087.5 Pa 

1 atm = 101,325 Pa 

P = Po + dgh 
h = (P - Po) / dg 
h = (35,014,087.5 - 101,325) / (1030 x 9.81) 
h = 3 455.23812 m 
h = 3.5 km
