An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

The difference is degree when used to describe temperatures. Warm is not as high a temperature as hot. Both are subjective terms. Warm, when used to describe an emotion instead of a temperature, means fond” or kind, while hot in that context could mean either sexy or angry.

temperature is the average kinetic energy of the particles of matter. the hotter something is the more kinetic energy it has.

A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic process is negative because the system is losing heat. Figure 8.7.

Classification Game! Mammals and birds are warm-blooded, which means that they can make their own body heat even when it is cold outside. Whether it is sunny and hot outside or there is a snowstorm and it is very cold, warm-blooded animals have body temperatures that usually stay the same.

Temperature. The temperature of an object is to do with how hot or cold it is, measured in degrees Celsius. ... When an object is heated, its particles move more vigorously and its internal energy increases. Unless the object changes state (eg melts or boils), its temperature will increase.

Temperature is the average kinetic energy of the particles. All particles are vibrating, and this is kinetic energy. Internal energy is the sum of the kinetic energy and potential energy stored in a system. Heat is is thermal energy being transferred because of a difference in temperature.

Warm and Cold Blooded Animals. With a few exceptions, all mammals and birds are warm-blooded, and all reptiles, insects, arachnids, amphibians and fish are cold-blooded.

Even if you have a high temperature, you might actually feel cold and begin to shiver. This is part of the first phase of having a fever. Your immediate reaction may be to huddle up under lots of blankets to feel warm. But even though you feel cold, inside your body is very hot.

The main difference between hot and cold desert is that the hot desert is battered by a high sun whereas the cold desert has ice and the snow in the ground. Furthermore, hot deserts are closer to the equator while cold deserts are in extreme northern or southern latitudes.

An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. ... So the reaction in which there is release of heat with or without light is called exothermic reaction.

Now when it comes to cold, a hot natured person will feel more comfortable at a cooler temperature than a cold natured. The friend I mentioned at the outset was starting to sweat at 60F degrees with no coat. I was standing beside him with coat buttoned all the way up to feel comfortably warm.

When used as nouns, cold means a condition of low temperature, whereas freezing means the change in state of a substance from liquid to solid by cooling to a critically low temperature. When used as adjectives, cold means having a low temperature, whereas freezing means suffering or causing frost.

With a few exceptions, all mammals and birds are warm-blooded, and all reptiles, insects, arachnids, amphibians and fish are cold-blooded. What does it mean to be warm-blooded or cold-blooded? The temperature of an animal's blood is related to its body temperature.

Endothermic reactions are the opposite of exothermic reactions. They absorb heat energy from their surroundings. This means that the surroundings of endothermic reactions are colder as a result of the reaction.

Humans are warm-blooded, with our body temperature averaging around 37C. Warm-blooded simply means we can regulate our internal body temperature, independent of environment, while cold-blooded animals are subject to the temperature of their surroundings.
