Anonymous users2024-02-051.The formula for calculating heat.
1) Endothermic formula: Q suction = cm (t-t0).
In the formula, c represents the specific heat capacity of the substance, m represents the mass of the substance, t0 represents the original initial temperature of the object, t represents the final temperature after endothermy, and "t-t0" represents the increase in temperature
Q suction = cm t liters.
2) Exothermic formula: q dissipation = cm (t0-t).
The meaning of c, m, t0, and t in the formula remains unchanged, "t0-t" indicates the decrease in temperature, and sometimes it can be expressed by t drop = t0-t, and the exothermic formula can be written as q release = cm t drop.
2.The general formula for calorific calculation: q=cm t
t denotes the change in temperature.
It can be seen that the amount of heat absorbed or released by the object is determined by the product of the mass of the object, the specific heat capacity of the substance and the change in the temperature of the object, and has nothing to do with the temperature of the object.
The units of each physical quantity in the formula of q absorption and q discharge:
The unit of specific heat capacity c is j (kg), the unit of mass m is kg, the single-brigade defense of temperature (t or t0 or t) is (degrees Celsius), and the unit of heat q is j.

Anonymous users2024-02-04Q suction is equal to cm, and the same is true for the one behind it, just change Q suction to bucket belt Q and put it. I'm very good at physics, but I don't remember formulas from the empty reeds, and I'm not neat, forgive me.

Learning at the high school level requires not only a lot of memorization, but also an improvement on the basics, a lot of thinking, and flexible responses in different situations. However, rote memorization has made the brains of some students ossify, and they forget that the learning method should change with the change in learning content. In high school, they still stick to the learning experience of junior high school and are unwilling to explore new learning methods, which is a manifestation of not adapting to new learning, in fact, it is also a kind of laziness and a kind of self-containment. >>>More
