Sodium chloride forms a crystalline lattice structure that is held together by strong ionic bonds between sodium and chloride ions, making it a harder substance. In contrast, glucose is a molecular solid with weaker intermolecular forces between individual glucose molecules. These weaker forces result in a lower hardness for glucose compared to sodium chloride.

Think critically how can the temperature of a substance remain the same even if the substance is absorbing thermal energy?
The substance could be undergoing a phase change, such as melting or boiling, where the absorbed thermal energy is being used to break intermolecular forces rather than increase temperature. Additionally, the substance could be acting as a reservoir for the thermal energy, buffering the temperature change by absorbing it without changing its own temperature until it reaches its heat capacity limit. Finally, the substance could be releasing an equivalent amount of energy through other means, such as radiation or convection, balancing out the absorbed thermal energy and maintaining a constant temperature.
Which compounds are added to increase weight of soap?
Compounds like sodium chloride (salt) or glycerin may be added to increase the weight of soap. These additives help to make the soap harder and increase its density, resulting in a heavier final product.
Name the hardest substance in the human body?
The hardest substance in the human body is tooth enamel. It is even harder than bone and serves as the outer protective layer of our teeth.
Why is it harder to boil water with salt?
Adding salt to water increases the boiling point of the water. This means it requires more heat energy to reach the higher boiling point, making it harder to boil the water with salt added.
Are diamonds the hardest substance known to man?
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
Is glucose a food for green plants?
harder
Does a change in temperature cause a change volume?
Yes, a change in temperature can cause a change in volume. When a substance is heated, its particles gain energy and move more vigorously, causing the substance to expand and its volume to increase. Conversely, cooling a substance causes its particles to lose energy and move less, leading to contraction and a decrease in volume.
Is lutetium harder than diamonds?
No. No substance known to exist is harder than diamond and especially no other element.

Is diamond harder then steel?
Yes, the mineral we know as diamond is harder than any steel. Diamond is the hardest substance we know of.
Can the temperature at which the egg is stored make the shell harder?
No.
What substance is made by a meteorite hitting earth that is harder than a diamond?
Nothing.
How do snow turn hard?
Snow will get harder as the temperature drops.
How does sodium chloride make water temperature colder?
Sodium chloride lowers the freezing point of water, causing it to freeze at a lower temperature than pure water. When sodium chloride is dissolved in water, it disrupts the hydrogen bonds between water molecules, making it harder for them to form ice crystals. This process requires energy, which is absorbed from the surroundings, resulting in a decrease in temperature.
Is it harder to raise the temperature of a rock than it is to raise the temperature of water?
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
Are Diamonds are the hardest substance on Earth?
It is the hardest NATURAL substance- due to the arrangement of the carbon atoms that make up a diamond. (Thee ARE harder materials, but they are manmade.)
What did they make steel out of?
Iron ore is purified with Carbon dioxide and it creates the harder substance steel
