What happened to the water when put inside the freezer? When you put liquid water into the freezer, the water loses energy to the cold air in the freezer. At first, the water molecules move more slowly. This means that the temperature of the water drops. Why is freezing a good method of preservation? Freezing […]

What are the elements in Group 0 called? Group 0 contains non-metal elements placed in the vertical column on the far right of the periodic table . The elements in group 0 are called the noble gases . They exist as single atoms . What is the relationship between group and valence electrons? The number […]

What ocean has the biggest waves? North Atlantic Ocean Is wind a wave? Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. How […]

Which is heavier 1 kg of steel? Steel is denser and thicker which leads to the fact that we believe it to be heavier due to the nature of the material. Notwithstanding, if we were to compare a small piece of steel that weighs 1 kg to 1 large bag of feathers that also weighs […]

What was the FEV1 at the initial radius of 5 mm? What was the FEV1 (%) at the initial radius of 5.00 mm? The FEV1 at the initial radius was 73.9%. Why is it impossible to further exhale the RV? Why is it impossible to further exhale the RV (that is, where is this air […]

What advantages does a radio telescope have? Radio telescopes detect radio waves coming from space. Although they are usually very large and expensive, these telescopes have an advantage over optical telescopes. They can be used in bad weather because the radio waves are not blocked by clouds as they pass through the atmosphere. What were […]

How do you find tension in a cable? We can think of a tension in a given rope as T = (m × g) + (m × a), where “g” is the acceleration due to gravity of any objects the rope is supporting and “a” is any other acceleration on any objects the rope is […]

What is the product of FeS HCl? Iron sulfide reacts with hydrochloric acid, releasing hydrogen sulfide: FeS + 2 HCl → FeCl2 + H2S. What type of reaction is Fe O2 → Fe2O3? Fe + O2 → Fe2O3 is the unbalanced form of chemical reaction. Fe + 3O2→ Fe2O3 there are now 6 O atoms […]

What is the definition of chemistry? Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. What type of science is chemistry Brainly? Chemistry is the science of matter and its changes […]
