You have two equivalent pots a and b with one liter and three liters of water respectively. both pots begin at 25 c then the same amount of heat is added to each pot. the three liter pot's final temperature is 35
c. what is the final temperature of the one liter pot?

Answer from: hiji0206

55 C

Explanation:

When a certain substance is heated, the temperature of the substance increases according to the equation

$Q=mC\Delta T$

where

Q is the heat supplied to the substance

m is the mass of the substance

C is the specific heat of the substance

$\Delta T$ is the change in temperature of the substance

The equation can be rewritten as

$\Delta T=\frac{Q}{mC}$

In this problem, the two pots both contain water, so the specific heat (C) is the same. Also, the same amount of heat is supplied, so Q is the same.

However, pot A contains 1 liter of water, while pot B containes 3 liters: this means that the mass of water in pot B is 3 times the mass of water in pot A,

m_B = 3 m_A

Since $\Delta T$ is inversely proportional to the mass, this means that

$\Delta T_A=3\Delta T_B$

The change in temperature of the water in pot B is

$\Delta T_B=35C-25C=10C$

So, the change in temperature of the water in pot A is

$\Delta T_A=3\Delta T_B=3(10)=30C$

So, the final temperature of pot A is

$T_A =T_0+\Delta T_A=25C+30C=55C$

Answer from: Quest

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like $\frac{1}{3}$ . (i crazy)

most famous scientist who contributed to this physics are:

max planckalbert einsteinerwin schrödingermany

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

superposition (where 1 thing can be this and that at the same time),entanglement (where two particles are seemingly connected by some sort of unknown (or known) force, energy, matter (i know all that can be the same at least it was at the beginning)

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
