Those molecules then come upon nearby debris and transfer a number of their power to them. They are very compressible (particles are widely spaced). He also shares personal stories and insights from his own journey as a scientist and researcher. Atoms fit together with other atoms to make up matter. In a gas, like helium, particles are widely spaced apart and move quickly and random directions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. Variation and Evolution Ecosystems Biodiversity Trophic levels Food production GCSE Chemistry random questions States of matter Elements, compounds and mixtures Atomic structure .

The specific latent heat of fusion is the energy needed to melt 1kg of a solid. Place 24 drops of water together to make one larger drop at the Start. Point out that the molecules of a liquid are in motion but they are attracted to each other. The random motion of smoke particles is evidence of the random motion of gas molecules, as many gas particles collide with a much larger smoke particle, pushing it around. Water molecules are made up of two elements - hydrogen (white atoms) and oxygen (red atoms). These biological molecules are composed of carbon, hydrogen, and oxygen molecules. Next, amino acids are made from nitrogen combined with glucose. Proteins are the primary building materials of the body. Students investigate a drop of water hanging from a dropper and drops of water beading up on wax paper. They see that the water holds together well and is not so easy to separate. Functional group determines their chemical properties. A liquid takes the shape of its container. As , EL NORTE is a melodrama divided into three acts. Use a popsicle stick to slowly drag the drop around the wax paper a bit. Alcohols are organic compounds. When a substance is heated, the particles have more kinetic energy. Our tips from experts and exam survivors will help you through. Polymer is a substance made up of a large number of smaller molecules that link together to form larger molecules. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. The density of a subtance is defined as its mass per unit volume. They have specific shapes and dimensions. Prepare two cards for each group. Being a solid, liquid, or gas is a property of a substance. metals. There are lots of different gases, such as the air we breathe or the helium used to fill balloons. The particle model represents particles by small, solid spheres. This is because the particles move faster with more kinetic energy. , depending on the type of substance, eg Today.

Conduction happens whilst a substance is heated, particles will acquire extra energy, and vibrate more. The atoms always join in fixed ratios and molecules have a specific formula, eg H. The size of the charge on the ion is equal to the number of electrons lost or gained. The goal is for students to begin thinking about water, or any substance, on the molecular level and to conclude that water molecules must be attracted to one another. giant molecules, and Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
