If a substance was described as smooth square and tan what properties are being referred to?
Smooth is what it feels like; square and tan are what it looks like - those would all be physical properties of the substance.
Is bubbling and fizzing a physical change or chemical change?
Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with the oxygen in the air and forms carbon dioxide. Since there is a new chemical composition of the soda since it has lost carbon, also know as going flat, this is a chemical change. The above example is incorrect. The bubbles coming out of soda is not carbon reacting with oxygen;the bubbles are already carbon dioxide. Does pencil lead react with oxygen? The carbon dioxide in your soda is dissolved in solution. Gas bubbles in most other situations though ARE a sign of a chemical change.

Is getting a sun burn a chemical change or a physical change?
"sunburn" results from physical damage caused to your skin by overexposure to Ultraviolet emissions, usually from the sun but it can also come from a UV lamp. UV light affects damage to the DNA of your skin cells. In defense those cells will produce melanin, a chemical response to try to repair this damage, which also darkens the color of the skin ( a "sun tan").

Is it suncream or sun tan cream?
The terms 'sun lotions' and 'sunscreens' are used interchangeably to describe many of them. 'Suntan lotion' is sometimes used to refer to substances designed to accelerate tanning with little or no sun protection factor. Some people use the term 'sunblock' to refer to sunscreens that reflect rather than absorb UV. Wearing a chemical- or physical-based sunscreen may help prevent the sun's rays from causing photoaging and skin cancer. You can find here best sunscreen

not unless it is from the sun no, the only reason that you get a tan is because melanin ( a chemical in a type of cell called a melanocyte in your skin) reacts when your skin comes into contact with UV light. Melanin is brown in colour hence why you go brown when you have been in the sun.
