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.
It is incorrect to say that an object "contains" heat because heat is not a tangible substance that can be stored within an object. Heat is a form of energy that can be transferred between objects or systems. When we say an object is hot, we actually mean that it has a higher internal energy due to the transfer of heat to it.
It is incorrect to say that an object has heat because heat is not a property that an object possesses; rather, it is the transfer of energy between objects due to a temperature difference. Objects can store thermal energy, but they do not "have" heat in the same way they have mass or volume.
chemiluminescence The direct production of light as the result of a chemical reaction with little or no heat produced
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.
It is incorrect to say that "heat rises" because heat does not have mass or volume to physically move in a specific direction. Heat transfer occurs from hot to cold areas due to the movement of thermal energy, known as convection, which leads to the misconception of heat "rising."

when the object contains more electrons than protons it becomes negatively charged or and Ion.
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.

It is wrong to say the temperature of an object is 23 degrees Kelvin because the Kelvin scale does not use the term "degrees." Instead, temperatures on the Kelvin scale are simply expressed in Kelvins. So, the correct way to state the temperature would be 23 Kelvin.

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!
I would call it "incalescent", but that's because I like obscure words. Someone who didn't enjoy reading dictionaries as a child might just say "hot".
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.
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.
