Which Is An Example Of A Chemical Change?, A Teaspoon Of Salt Dissolves, A Candle Burns, A Pan Of Water Boils, A Burner Gets Red Hot

Which is an example of a chemical change?

a teaspoon of salt dissolves

a candle burns

a pan of water boils

a burner gets red hot

 

An example of a chemical change : a candle burns

Further explanation

In chemical reactions there will be several indications of chemical changes. This indication can be:

  • light
  • discoloration
  • smoke arises
  • give off heat etc.

In Physical changes the properties of the particles remain the same.

  • a teaspoon of salt dissolves

Salt will only dissolve into a solution, without producing new substances, and salt can be recovered for example by evaporation, so that it includes physical changes

  • a candle burns

In this condition 2 changes can occur

Physical changes  because the shape of the candle changes from solid to liquid (melts)

Chemical changes due to combustion reactions that produce light and smoke

  • a pan of water boils

Only changes occur from liquid to gas, so that including physical changes  

  • a burner gets red hot

Burner material does not change, only changes in temperature to high temperature so that the burner becomes hot and red, so it includes physical changes

Action Plan: What Is The Title Of Your Study?

Action Plan: What is the title of your study?   Answer: The Stressful Environments and our bodys Responses around them Explanation: Our bodies, families, communities and lives are embedded in a complex network of systems. The degree of support in the environment can shape a person's resilience. Likewise, an environment that is stressful can foster disease. The conditions of a person's social and psychological environment—those in which they are born, grow, live, work and age—are known as the social determinants of health. These conditions are shaped by the distribution of money, power and resources at global, national and local levels. Risks for Stress: Riskscapes A riskscape, or landscape of risks, captures the overlapping threats to health occurring in a physical location that increase risk for disease. An example of overlapping risks can be seen in impoverished neighborhoods, which often experience many of the stressors listed above simultaneously. We discuss poverty i...

Ito ang mga pangunahing kasagutan sa kung ano ang ibig sabihin ng ekonomiks. Ngunit sa mata ng iba't-ibang ekonomista, ang kasagutan sa katanungan na kung ano ang kahulugan ng ekonomiks ay may iba't-ibang pagpapaliwanag na maaaring magbigay ng mga simpleng kahulugan ng ekonomiks. Ang makabuluhang kahulugan ng ekonomiks ay ...
