What are the signs of an exothermic reaction?
The reaction vessel will warm/hot to the touch. 'Exothermic' ; het coming out. Conversely, if the reaction vessel feels cool/cold to the touch it is Endothermic ; taking in heat from its surroundings.
Why ammonium chloride in water becomes cold?
When ammonium chloride dissolves in water, it undergoes an endothermic reaction, meaning it absorbs heat from the surroundings. This absorption of heat causes the temperature of the solution to decrease, and as a result, the solution feels cold to the touch.
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
This is an example of an endothermic chemical reaction, where energy is absorbed from the surroundings in the form of heat, causing the pack to become cold. The reaction between the chemicals in the instant cold pack and water absorbs heat from the environment, resulting in the cooling effect.
Is a test tube that feels cold to touch after two substances have been mixed is exothermic?
NO. If the test tube becomes hot, then the reaction taking place in the test tube is EXOTHERMIC. The reaction is releasing heat to the surroundings, and the test tube is part of the surroundings.
What statement correctly describes an endothermic chemical reaction?
An endothermic chemical reaction absorbs heat from its surroundings, causing a decrease in temperature. This type of reaction typically feels cold to the touch and requires an external heat source to proceed.
What most determines how hot or cold something feels when you touch it?
Heat flow determines how hot or cold something feels when you touch it.
Which factor most determines how hot or cold something feels when you touch?
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
The marble floor feels cold to touch?
Slippers?

What does an endothermic reaction feel like?
An endothermic reaction feels cold because it absorbs heat from its surroundings. This can sometimes give the sensation of cooling or a decrease in temperature.
What glass feels like when you touch it?
Smooth, slippery and cold.

An ice cube feels cold when you touch it because your body loses heat by?
convection
What does it mean when your pee is cold?
Your urine comes out at body temperature, which even if dangerously low, would not feel cold to the touch. If your pee feels cold to you it is because it is wet and just feels that way without actually being cold.
