An endothermic reaction is favored by raising the temperature of a system in dynamic equilibrium. The mechanism absorbs the increased heat to offset the alteration you made. An exothermic reaction is favored by a system's temperature falling while it is in dynamic equilibrium.
<h3>Which of these reactions is endothermic?</h3>
Any chemical process that takes heat from its surroundings is said to be endothermic. The reaction's activation energy comes from the energy that was absorbed. This kind of reaction is characterized by its icy sensation.
<h3>How does an exothermic reaction work?</h3>
An exothermic reaction is one in which energy is given off as heat or light. In contrast to an endothermic process, which draws energy from its surroundings, an exothermic reaction transfers energy into the environment.
<h3>What kind of reaction is an exothermic reaction?</h3>
Materials like hydrocarbons reacting with oxygen to produce combustion products like water and carbon dioxide is an example of an exothermic process.

Answer:
The correct answer will be
Test variable or dependent variable- The time required to melt the ice cube
Explanation:
In a scientific experiment, three types of variables are kept and studied which includes: The independent variable, dependent variable and the constant variable.
Among these three, the variable to be tested is known as the dependent variable which is influenced by the independent variable which changes.
In the given question, since the experiment was performed to test the rate of the release of heat by a different substance which could be tested by measuring the rate or time required to melt the ice cube which depends on the type of casserole.
Thus, the time required to melt the ice cube is the correct answer.
Answer:
H20
Explanation:
H20 (WATER) is a compound because its constituent atoms, oxygen and hydrogen are present in a definite ratio (1:2)
Answer:What kind of milk? What are the variables on your project? (I'm assuming it's an experiment)
Explanation:
The last option, 1 meter/ 10 millimeters is not a valid conversion factor.
It should be 1000m Instead of 1 meter/ 10 millimeter since 1m=1000mm
