Answer:
True
Explanation:
The given statement is true.
A scientific model is defined as the mathematical and physical representation of a process or event. Scientists perform several observations or experiment and find a connection between them to prove a scientific finding.
A scientific model has the ability of explanatory power which helps to make things easier to understand using diagrams and consistency across contexts. Testing and prediction power in scientific models leads to strong predictions and able to convince people using an appropriate model.
Hence, the correct answer is "true".
<span><span />It is water’s Ionization Property. Water
Ionization also known as self-ionization or auto ionization of water creates a
positive and Negative ion which is essential for chemical reactions. It is a
reaction of pure water in where a water molecule and H2O combined to make a
hydroxide ion. It usually occurs due to the electric field fluctuation between
2 neighbouring molecules. It is a property of pure water that mixed or
dissociates to from a new substance which is a hydrogen ion (positive ion) and
hydroxide ions (negative ion)</span>
I'm pretty sure a physical change because it's affecting the form of the chemical substance, but not its chemical composition
During the melting of ice in the mouth, the mouth loses heat and feels colder.
<h3>What is the heat change that occurs in melting?</h3>
Melting is the process by which when a solid absorbs heat from the surroundings, it changes to liquid.
Therefore, the melting of a solid is an endothermic process.
In the system of ice melting in the mouth, the ice molecule absorbs heat energy from the mouth in order to melt.
Similarly, when the temperature of the water rose to 10.0 degrees, the water at 0.00 degrees absorbs heat from the mouth.
Therefore, the mouth loses heat and feels colder.
In conclusion, the melting of ice involves ice absorbing heat from the surroundings.
