## What is the equation for Q?

We wish to determine the value of Q – the quantity of heat.

To do so, we would use the equation Q = m•C•ΔT.

The m and the C are known; the ΔT can be determined from the initial and final temperature.

With three of the four quantities of the relevant equation known, we can substitute and solve for Q..

## What is K and Q in chemistry?

Consider a simple chemical system including just two compounds, A and B: Q is a quantity that changes as a reaction system approaches equilibrium. … K is the numerical value of Q at the “end” of the reaction, when equilibrium is reached.

## What does Q stand for in chemistry thermodynamics?

HeatHeat in thermodynamics Scientists define heat as thermal energy transferred between two systems at different temperatures that come in contact. Heat is written with the symbol q or Q, and it has units of Joules ( Jstart text, J, end text).

## What is Q MC ∆ T used for?

The quantitative relationship between heat transfer and temperature change contains all three factors: Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.

## How is Q value calculated?

Here’s how to calculate a Q-value:Rank order the P-values from all of your multiple hypotheses tests in an experiment.Calculate qi = pi N / i.Replace qi with the lowest value among all lower-rank Q-values that you calculated.
