What else can I help you with?
How can a thermometer be used to help you decide whether your observation is physical or chemical change?
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
How can you identify that a change is chemical?
A change is chemical if the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Look for indicators such as color change, gas production, temperature change, or formation of a precipitate to help identify a chemical change.
Why is it important to observe temperature change when two chemical are mixed?
Observing temperature change when two chemicals are mixed can provide insight into whether a chemical reaction has occurred. An increase or decrease in temperature may indicate that the reaction is exothermic or endothermic, respectively. Monitoring temperature change can also help determine the reaction rate and the efficiency of the reaction.
What is the impact of a change in temperature on the delta S of surroundings in a chemical reaction?
A change in temperature can affect the entropy change (delta S) of the surroundings in a chemical reaction. When the temperature increases, the surroundings absorb more heat energy, leading to an increase in entropy. Conversely, a decrease in temperature results in a decrease in entropy of the surroundings.
Which are 4 indications of chemical reaction has occurred?
The indicators of a chemical reaction are :- 1. Change in colour 2. Change in temperature 3. Evolution of a gas 4. Formation of a precipitate
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
Is temperature change chemical or mechanical?
chemical
Why does a chemical change in temperature indicate that a chemical reaction may have occurred?
A change of temperature implies that some energy has been transfered or used. Since chemical reactions either require or release energy to occur, the environment may change temperature as the substances react.
Does a chemical change create a temperature change?
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
Why does a change in temperature indicate that a chemical reaction may occur?
Because a chemical reaction has different sign's. And heat is one. But if the temperature is dropping then it is not going through a chemical change.
Can temperature change chemical properties?
yes it can!!
What clues can you use to identify a chemical change?
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
What can be used as an indicator fot a physical change and a chemical change?
A temperature change can be seen both in physical and chemical changes.
Would something turning hot to cold be a chemical change?
A decrease in temperature is a physical change, not chemical.
When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
Yes, a chemical change can still occur without a noticeable change in temperature. Some chemical reactions are endothermic (absorb heat) and others are exothermic (release heat), so observing a change in temperature is not always a reliable indicator of a chemical change taking place. Other signs to look for include color changes, gas production, formation of a precipitate, or the release of light.
Is temperature physical weathering or chemical weathering?
Temperature change is a physical phrenomenon.
