It isn't wrong to say an object contains heat because the concept of comparing heat to a liquid that can be 'poured' from one object into another creates a perfectly valid model for understanding thermodynamics and performing calculations.
For example:
Consider a sample of water to represent an object such as a bowl and the level of the liquid in the bowl to represent temperature. The volume of the liquid in the bowl would represent the heat.
You would need to pour comparatively more heat into the bowl to cause the same rise in temperature as you would into a narrow vase. A narrow vase would represent an object that has less heat capacity than water, such as most metals.
When you allow two substances in contact to come to the same temperature it is the same as pouring heat from one object into the other.
At the same temperature, an equal mass of water contains more heat than a piece of metal at the same temperature. The ratio of the change in temperature of an object to that of water gives the specific heat (C) for that substance.

Why is it incorrect to say that an object has heat?
because not all objects have heat and because the heat is coming from your hands
Does heat describe how hot or cold something is?
The term heat can refer to something being hot or cold. If an object is hot, you could say that it has a lot of heat, and if it is cold, you could say that it has very little heat. However it should be noted that heat and temperature are not quite the same thing. A bathful of lukewarm water contains far more heat, or thermal energy, than a lit candle. Though the candle has a higher temperature.
What is the emission of heat from an object called?
chemiluminescence The direct production of light as the result of a chemical reaction with little or no heat produced
What is the mechanical energy of an object?
Mechanical energy is heat light and kinetic energy but instead of saying something has heat light and kinetic energy we just say mechanical! :)
Why 2 objects at the same temperature will have different amounts of energy if one has a larger mass?
All objects have a specific heat capacity, the amount of energy it takes to increase the temperature of one gram of the object by one degree centigrade. Therefore, if an object has a specific heat capacity of say, 500 joules, and you wanted to heat 3 grams of that object by 1 degree, you would need 1500 joules of energy. But if you put that 1500 joules of energy into only 1 gram of the object, you would heat it by 3 degrees.
Why is it wrong to say the temperature of an object is 23 degrees kelvin?
it is incorrect to say the temperature of an object is 23 degrees k. Why?

When do you say that an object is negatively charge?
when the object contains more electrons than protons it becomes negatively charged or and Ion.

Does microwave gives out heat?
It would be more accurate to say that microwaves can be converted to heat. A microwave oven is designed speicifically to heat water, or anything that contains water.

chemiluminescence The direct production of light as the result of a chemical reaction with little or no heat produced
Is this ok for for explaininng something simply about Heat and Temp Heat How hot or cold something is Temp The amount of energy in the particles?
I'd say you want the explanations exactly the other way around: Temp . . . how hot or cold the whole object is. Heat . . . the amount of energy in the object's particles.
What is the mechanical energy of an object?
Mechanical energy is heat light and kinetic energy but instead of saying something has heat light and kinetic energy we just say mechanical! :)
Let's say there are two objects Object 1 has a high specific heat and Object 2 has a low specific heat Which object would heat more I'll give trust point and recommend contributor?
Heat energy (gained/lost)= mass x specific heat capacity x temperature(rise/fall) Now with this expression we come to know that for a given mass and with a given amount of heat energy in joule, as sp. heat cap is more then rise / fall in temperature will be less and vice versa.
Why is it incorrect to say that matter contains heat?
Heat is not an internal property of matter (temperature is!), heat is just a way to change the temperature of an object... it is a flow of energy. Think of it this way, before you study for a physics test you have a certain level of understanding physics. While you read your text book (or wiki answers) you are studying (understanding is flowing into your head) and afterward you (hopefully) have a greater understanding of physics. Although "studying" went into you, you do not have a certain amount of "study" inside of you before or after, you had an amount of understanding. In that analogy, "studying" represents heat and "understanding of physics" represents temperature. Heat is just a way to change temperature and therefore you cannot say that matter contains heat!
Do tortoises hibernate in straw?
I would say no, but I could be wrong. Mine likes to dig in his dirt next to a heat pad.
Why is it wrong to say that 50c helium is twice as hot as 25c helium?
because the centigrade scale has 0 where there is not 0 heat
