Thermal energy will flow from an object high temperature to an object of low one. In this case, the thermal energy will flow from object B to object A.
IgorLugansk [536]2 years ago

Explanation:

Internal energy which is present within the molecules of an object due to the kinetic energy of its particles is known as thermal energy.

Thermal energy will always flow an object with high temperature towards an object with low temperature only when both the objects are placed in contact with each other.

For example, when object A has a temperature of 287 Kelvin, and object B has a temperature of 374 Kelvin. Then thermal energy will from from object B to object A.

Gravity is the force of motion pulling down objects to the ground. If there was no gravity, everyone would walking as if they were on the moon.


Mass is what gravity needs. If an object has a little amount of mass, gravity will be able to easily bring it to the ground.


If an object has a very huge amount of mass, gravity will still be able to bring it to the ground but it will be hard.


For example: An airplane has a HUGE amount of mass. Gravity pulls it down but the airplane needs to be steering up in order for it to be straight. Gravity is applied on the airplane when it is landing.

BUT..... if a table is in the way of an object it depends if it will fall down to the ground or stay on the table.

If an object has little mass and a table is in the way of gravity pulling it down to the ground, the object will stay on the table. Like a plate of food on a table.

If an object has a very big amount of mass and a table is in the way of gravity pulling it to the ground, the object will break the object and make it's make to the ground. That is mostly why most of the time people have very strong tables/ anything to hold a heavy object.  


Another example is if you're lifting weights and you have little amount of mass, you're most likely to get the little sized weight. It depend on you mass.


Here are some pictures I included here as well of Mass and gravity.

Glad to help! :) :D

Calculate the osmotic pressure of 20 m solution of <br> LiCl at 25C
Soloha48 [4]

Answer:

979 atm

Explanation:

To calculate the osmotic pressure, you need to use the following equation:

π = <em>i </em>MRT

In this equation,

-----> π = osmotic pressure (atm)

-----><em> i</em> = van't Hoff's factor (number of dissolved ions)

-----> M = Molarity (M)

-----> R = Ideal Gas constant (0.08206 L*atm/mol*K)

-----> T = temperature (K)

When LiCl dissolves, it dissociates into two ions (Li⁺ and Cl⁻). Therefore, van't Hoff's factor is 2. Before plugging the given values into the equation, you need to convert Celsius to Kelvin.

<em>i </em>= 2                             R = 0.08206 L*atm/mol*K

M = 20 M                    T = 25°C + 273.15 = 298.15 K

π = <em>i </em>MRT

π = (2)(20 M)(0.08206 L*atm/mol*K)(298.15 K)

π = 979 atm
