If a cook puts 9.00g of water in a 2.00 -L pressure cooker that is then warmed to 500°C, the pressure inside the container is 15.8 atm.
<h3>What is the pressure inside the container?</h3>
From the ideal gas law;
PV = nRT
Where P is pressure, V is volume, n is amount of substance, T is temperature and R is the ideal gas constant (0.08206Latm/molK).
Given the data in the question;
- Mass of water m = 9.00g
- Volume V = 2.00L
- Temperature = 500°C = ( 500 + 273.15)K = 773.15K
- Pressure P = ?
First we determine the amount of water n.
We know that the molar mass of water is 18.01528 g/mol.
Hence
n = mass / molar mass
n = 9.00g / 18.01528 g/mol
n = 0.4995mol
Now, plug the values into the equation above and solve for P
PV = nRT
P = nRT / V
P = ( 0.4995mol × 0.08206Latm/molK × 773.15K ) / 2.00L
P = ( 31.6906Latm ) / 2.00L
P = 15.8 atm

The correct answer that would best complete the given statement above would be INCLINED PLANES. Screws and wedges are modified inclined planes. An inclined plane that moves is called a wedge and a screw is the result when <span>you take an inclined plane and wrap it around a cylinder. Hope this answer helps you. </span>
(I'm not sure what the unit "m1" is. Do you mean ml for milliliters? I am going to use ml in this problem.)
Volume= 130ml
Mass= 585g
The formula for density is
Density=Mass/Volume
All you have to do is pop the information in the formula Density= 585g/130ml
585/130= 4.5
you can't divide g/ml, so just leave it the way it is
Therefore the answer is
Density= 4.5 g/ml
Hope this helps!
Answer:
If the force on a cart doubles, the acceleration of the cart doubles.
Explanation:
For this problem, we need to consider the following equation:
Force = Mass x Acceleration
We can reasonably assume that the cart will have constant mass in the given force system. With this assumption we can say the following relationship:
Force is directly proportional to Acceleration within the system.
Given that our force on the cart is doubled, then our acceleration of the cart must also be doubled. You can mathematically express this as follows:
F = MA
2F = M * 2A
Hence, if force doubles, the acceleration doubles.
Cheers.
Answer:
tension
Explanation:
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration.
