A chemical change occurs when two or more substances join to form new substances with new physical properties.
What is physical property?Physical property of a substance is defined as a property that can be measured and the value explains the state of a physical system. Physical properties can be observed and measured without changing composition.
Physical properties of matter are malleability, solubility, density, conductivity, color, hardness, and electrical conductivity. A change in physical properties is due to physical change and it is a characteristic of a particular substance that can be observed without changing the identity of the substance.
Chemical property is that chemical property can be observed or measured while a substance undergoes in a chemical change.Physical properties of matter are malleability, solubility, density, conductivity, color, hardness, and electrical conductivity.
Therefore,A chemical change occurs when two or more substances join to form new substances with new physical properties.

Compare pressure that fluid applies to the bottom of a glass with the pressure it applies to the sides of the glass
Answer:
The pressures that fluid applies to the bottom of a glass is comparably more than the pressure it applies to the side of glass because as we know liquid pressure is increased with depth where the bottom of galss have more depth than sides
The pressure at the bottom of the glass is more as compared to the sides of the glass because the pressure increases with increase in depth.
What is pressure?
Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.

Explanation:
Hope this helps
Elements which are most similar to neon are helium,argon,krypton,xenon and radon as they have similar outer electronic configuration.
What is electronic configuration?
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
