What else can I help you with?
Can water be made to boil at 95 or 105C?
Yes. The temperature can be reduced by lowering the "atmospheric" pressure: for example by going up a mountain. The boiling point can be raised by increasing the pressure - in a pressure cooker, for example, or by dissolving a solute such as salt.
When volume increases does mass increase?
This is not entirely true. The mass will only increase with volume if you are adding more to to increase the volume. However, you can increase the volume without increasing mass. An example of this would be heating something. As you heat things the molecules want to move about more, as this happens they spread further and further apart. This is easiest to observe in when things are in a gaseous state. You can determine how the volume of a gas changes by PV=nRT; where P is pressure, V is volume, n is he number particles, R is constant, and T is the temperature in Kelvin.
Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.
What is the density anomaly?
Density anomaly refers to a situation where a substance does not follow the typical trend of increasing or decreasing in density with a change in temperature. For example, water has a density anomaly where it reaches its maximum density at 4 degrees Celsius, causing it to behave differently from most other substances.
Some elements have been made by scientists under laboratory conditions?
There are many. Number 43 (technetium) and numbers 84-118 are also made in laboratories. However, numbers 90, 91 and 92 are found in nature but they're also made in laboratories. They are made by throwing different atoms in each other. For example, ununoctium was made by throwing californium atoms in calcium atoms.
What is example of increasing friction intentionally?
well immediatly when i hear the word friction i think of tires and u need to add something to make it intentionally go faster so an example would be " adding grease to gears on a bike." Heather - 14 - MI ^^^ this is decreasing friction. Adding friction would be like throwing sand on a icy driveway so you don't slide..
What is an example of in reading friction intentionally waxing skis throwing sand on an icy driveway adding grease to gears on a bike or oiling a squeaky door?
Using sandpaper to increase friction on a slippery surface, such as on the bottom of shoes for better grip.
Which of following is an example of increasing friction intentonally?
Adding sandpaper to the bottom of a sled to slow it down is an example of intentionally increasing friction.

Is waxing skiis an example of increasing friction intentionally?
Yes, waxing skis is an example of intentionally increasing friction. The wax creates a rough surface on the ski base that interacts with the snow, providing more grip and control when skiing downhill.
What as an example of increasing friction intentionally?
assuming that you're asking a multiple choice question, waxing skis reduces friction so that you can move faster on the snow. grease and oil are used as lubricants. they reduce friction in most instances. throwing sand on an icy driveway would increase friction between a cars tires and the ice. a good rule of thumb is that most liquids work as lubricants, most gritty or solid stuff works to increase friction, and powder can do either.
What is an example of increasing friction intentionallly?
One example of intentionally increasing friction is by roughening the surfaces that are in contact, such as adding sandpaper to the bottom of a shoe to increase grip. Another example is tightening the screws or bolts holding two surfaces together to create more friction between them.
What are examples sentence with the word driveway?
Example sentence - I parked my car in the driveway each night.
Is driveway an example of inclined plane?
that depends on whether or not the driveway is on a hill. if the driveway is flat, it is not in inclined plane. if it is on a hill then yes it is an inclined plane
What does intentionally mean?
to do something intentionally is to do it on purpose, to mean to do it - for example 'I hurt you intentionally'
Examples of negative reinforcement?
An example of negative reinforcement, a child screaming because they do not want to eat, and the parents taking the food away. Another example, would be a parent throwing out clothing a child doesn't like because the child intentionally tore the clothing.
An example of kinetic energy is?
Throwing a ball is an example of Kinetic Energy.
