Endothermic and exothermic are both terms used for the transfer of heat through a chemical reaction. When the mixed chemicals give off more heat than before (Become hotter), than an exothermic reaction has occurred. This is where energy is given off to the surroundings, causing the temperature to rise. Exothermic reactions are the opposite to this, where the container holding the chemicals becomes colder. This is because energy was required and heat was taken from the surroundings for the reaction to occur. Hope this helps.
No, fractional distillation of oil is not an exothermic process. It is a physical separation process that relies on the differences in boiling points of the components in the crude oil mixture. Heat is added to vaporize and separate the components, making it an endothermic process.
The difference in potential energy between the reactants and products.
One key physical difference between transition metals and poor metals is that transition metals have high melting and boiling points compared to poor metals. Transition metals also tend to be more malleable and ductile, while poor metals are typically softer and have lower melting points.
The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.
The extraordinary difference in melting points between cyclohexane and cyclohexene is due to the difference in shape. Cyclohexene has an awkward geometry to stack with sp2 hybridized bond angles. This lends to an extreme low melting point for cyclohexene.
Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... This is wrong it is exothermic. Potassium chloride is snow salt. it is used because not only does it react with the snow to create hydrochloric acide and potassium hydroxide (both with much lower freezing points) but, the EXOTHERMIC reaction also helps melt the snow No, it is endothermic. The only reason we add salt to snow is to lower the melting point. If you're curious, dissolve as much KCl in a beaker as you can as quickly as you can. The water temperature will drop dramatically.

The difference between the freezing and boiling points vary from substance to substance.
The difference in potential energy between the reactants and products.
The difference between -18 and 68 is 86.
The phase difference between points e and f is the difference in the position of their respective waveforms at a given point in time.
The pressure difference formula is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points. To calculate the pressure difference between two points, you can use this formula by plugging in the values for the density of the fluid, acceleration due to gravity, and the height difference between the two points.
To determine the potential difference between two points in a circuit, you can use a voltmeter. Connect the voltmeter across the two points you want to measure and the reading displayed on the voltmeter will indicate the potential difference between those two points.
The rise is the difference between the ordinates (vertical values) of two points on a line whereas the run is the difference between their abscissae (horizontal values) of the same two points.

because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
