tension can be broken by adding soap to water. Gases An airlike fluid substance which expands freely to fill any space available‚ irrespective of its quantity. Examples: Water vapor‚ Hydrogen‚ Oxygen Plasma seen in ionized gases distinct from a gas because it possesses free electrical charges (not bound to atoms or ions) cause plasma to be electrically conductive. Examples: Stars‚ Lightning‚ fluorescent lights Melting(Endothermic) Become liquefied by heat. Melting point-the temperature

Matter In Our Sourroundings Important Questions Not for coping to note Q. 1. What is a matter? Answer : Anything that occupies space and has mass is called a matter. For example:- Chalk‚ Milk‚ Sugar etc. Q. 2. Sodium chloride and sugar have same appearance. Are they same or different? Answer : They have different physical and chemical properties. So‚ they are different. Q. 3. All substances around us are alike. How? Answer : All substances can occupy space and have weight.

Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given mass of a gas exerts is inversely relate to its

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

sulphur dioxide gas counter-currently reacting with Na2SO3 rich feed. Introduction Absorbers are vertical towers used in distillation‚ gas absorption and liquid-liquid extraction processes. Absorbers can be operated co-currently or counter currently. In the former‚ both fluids involved are fed into the unit from the same point causing them to flow along each other. In counter current operation‚ the liquid is fed at the top of the absorber‚ flows downwards and contacts with rising gas fed from beneath

HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper and gas delivery plastic system on the test tube and arranged the tube in the well plate. I then took the test tube filled with water inverted it and placed on top of the gas delivery system‚ I had the well plate in a large bowl in case of flow over. I then removed and placed my thumb over the opening so gas wouldn’t escape I lit a match and held it approx 1 cm away and allowed a small drop from the pipet

I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water‚ and hydrogen peroxide in order to create the gases to be tested.
