It is difficult to determine without additional information.
It seems that the question is asking which changes shown in the table are physical changes.
Based on the information provided, the options are:
1. 1 and 2
2. 2 and 4
3. 1 and 4
4. 2 and 3
To determine which changes are physical changes, we need more information about each change in the table.
To determine which changes shown in the table are physical changes, we need to understand what a physical change is. A physical change is a change that does not result in the formation of a new substance. It only alters the physical properties of a material, such as its shape, size, color, or state (solid, liquid, gas).
Let's analyze each option in the question:
1. Option "1 and 2": If both changes 1 and 2 react with another substance, it indicates a chemical change and not a physical change. So, we can eliminate this option.
2. Option "2 and 4": If both changes 2 and 4 react with another substance, it indicates a chemical change and not a physical change. So, we can eliminate this option.
3. Option "1 and 4": This option includes changes 1 and 4. Without knowing the specific details of changes 1 and 4, it is difficult to determine whether they are physical changes or chemical changes. So, we cannot yet confirm this option.
4. Option "2 and 3": If both changes 2 and 3 do not react with another substance, it suggests a physical change. So, this option is a possible answer.
Therefore, the possible answer to the question "Which changes shown in the table are physical changes?" is "Option 2 and 3."
Now, moving on to the next question:
To determine if there is a temperature change, gas, sound, or light produced, we can look at the provided information:
1. For change 1: There is no information given about temperature change, gas, sound, or light produced. We cannot confirm anything.
2. For change 2: There is no information given about temperature change, gas, sound, or light produced. We cannot confirm anything.
3. For change 3: There is information that indicates a temperature change, as the word "yes" is provided. It suggests that there is a temperature change. We can confirm this.
4. For change 4: There is no information given about temperature change, gas, sound, or light produced. We cannot confirm anything.
Therefore, based on the information provided, we can confirm that for change 3, there is a temperature change.
Lastly, for the question "New substance formed?" we can see that no specific information is given for any of the changes. Without any information about the formation of a new substance, we cannot determine if a new substance is formed or not. So, we cannot answer this part of the question.
In summary, the answers to the given questions are:
1. Which changes shown in the table are physical changes? The possible answer is "Option 2 and 3."
2. Temperature change? Change 3 shows a temperature change.
3. Gas, sound, or light produced? No information is given for any of the changes.
4. New substance formed? No information is given to determine if a new substance is formed.
