Is a burning wood into ashes and smoke a physical or chemical change?
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
Is a firework a physical or chemical change?
A firework undergoes both physical and chemical changes. The lighting of the firework involves a chemical reaction within the firework's composition to produce the colors and effects seen in the sky. The transformation of the firework materials into smoke and ash after the display represents a physical change.
Is a broken glass a chemical hazard?
Not directly. It can be a physical hazard. The only connection to chemical hazards is that dangerous chemicals might be stored in glass containers, and released by breakage. Laboratory containers may contain many dangerous chemicals, and individual chemicals that are dangerous if combined.
Is burning a sticky note a chemical or physical change?
Burning a sticky note is a chemical change. It involves the combustion of the paper, which results in the production of new substances, such as ash, smoke, and gases.
What are some steps to physical and chemical change?
Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.
What are the different of hazard?
physical hazard,mechanical hazard,chemical hazard,electric shock hazard,crt monitor high voltage hazard.
How would you differentiate the effect of physical hazard from biological hazard and chemical hazard?
physical hazard affects you physically but a biological or chemical hazard affect you from within. Physical hazards may cause injuries such as broken leg, cuts, wounds, etc. while biological/chemical hazards can cause injuries such as choking, inability to breath, internal bleeding .
What are the kinds of hazard?
physical hazard,mechanical hazard,chemical hazard,electric shock hazard,crt monitor high voltage hazard.
Does smoke of a vehicle a physical or chemical change?
The smoke produced by a vehicle is a combination of physical and chemical changes. The combustion of fuel in the engine is a chemical change that produces gases, while the dispersal of these gases into the air involves physical changes such as condensation and diffusion.
What type of hazard is an allergen?
what type of hazards like bio logical, chemical or physical
Is smoke a physical change?
It's not a physical change. Rather, it is a sign of an already completed chemical reaction.
What is a cbrn hazard marker for a chemical hazard?
what is a CBRN hazard marker for a chemical hazard
What are the different types of hazard in the work place?
physical, chemical, biological, ergonomic and psycological hazards
Is smoking a cigarette a physical or chemical change?
Smoking a cigarette involves a combination of physical and chemical changes. The act of lighting the cigarette and burning the tobacco involves a chemical change, producing new substances. The process of inhaling and exhaling the smoke is a physical change as it involves a change in state (from solid to gas) without altering the chemical composition of the smoke.
Is dry ice changing into theatrical smoke physical or chemical change?
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
Black smoke from candle physical change or chemical change?
The black smoke produced from a burning candle is a physical change. This is because the change in appearance (from no smoke to black smoke) does not involve a change in the chemical composition of the candle wax or the oxygen in the air. The black smoke is primarily made up of tiny carbon particles that result from incomplete combustion of the candle wax.
What is the three main type of contamination?
Biological, Chemical, Physical These are the 3 hazard categories used in HACCP plans.
