What else can I help you with?
Does a temperature change indicate a physical change?
Yes, it is possible.
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.
What does the TC indicate on calibrated instruments?
The TC on calibrated instruments indicates the temperature coefficient, which shows how the instrument's accuracy may change with temperature variations.
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 are four things that indicate that a chemical change probably happened?
Four things that indicate a chemical change probably happened include color change, formation of a precipitate, evolution of gas, and change in temperature. These signs suggest that a new substance with different chemical properties has been formed.
What property of a substance does the change in temperature indicate?
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
The precipitation of a solid can indicate a?
chemical reaction taking place, a change in temperature or pressure, or the formation of a new phase in a solution. It can also be used as a method for separating components in a mixture or as a way to purify a solution.
Is this true or false a change in temperature is always an indicator of a chemical reaction?
False. A change in temperature can indicate a chemical reaction, but it is not always the case. Temperature changes can also result from physical changes, such as phase transitions (e.g., melting or boiling). Therefore, while temperature change can be a sign of a chemical reaction, it is not a definitive indicator on its own.
What would this physical change most likely indicate about changes in the status of the pond?
A decrease in temperature has moved the algae into the stream.
What is the purpose of a temperature indicator?
To indicate the temperature?
What are four things that indicate that a chemical change probably happened?
Production of gas: If there is a sudden release of gas, bubbling, or fizzing, it may indicate a chemical change. Formation of a precipitate: A solid substance forming in a solution can indicate a chemical change has occurred. Color change: A visible change in color of the substance can be a sign of a chemical reaction. Change in temperature: A noticeable temperature change, either an increase or decrease, can be an indicator of a chemical change taking place.
What is an example of a color change that does not indicate a chemical reaction?
Many materials can change colour according to the temperature without there being any chemical reaction taking place.
