I need a question to answer lol
Answer:
Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces. Water also has a high specific heat.
Explanation:
Hope this helped it is what I could find!
Answer : The density of a sample is, 34.2 g/L
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used for density :
Given :
Mass of a sample = 7.412 grams
Volume =0.217 L
Now put all the given values in the above formula, we get the density of a sample.
Therefore, the density of a sample is, 34.2 g/L
Answer: You can increase the weight, then test the speed, and make the weight normal and test the speed, and mark which one travels faster.
Explanation: This would test your hypothesis by comparing the speeds of the cars when more mass is added. Calculating the difference of the speed with more mass, and the speed with normal mass would give you your answer. A positive number would prove your hypothesis and a negative number would disprove it.
