What happens to a sample of water when it is heated between 4 degrees c and 100 degrees c?
4 degrees celcius is the temperature at which water has it's highest density. As it goes lower towards freezing, it actually expands (one of waters most interesting and important attributes)
As you heat water from 4 degrees celcius, it gradually looses it's density, and steadily comes closer to crossing the threshold of boiling.
Fun fact:
Why is it that the bathroom is full of steam after i've showered, when the water wasn't nearly hot enough to be turning in to it's gas form (which it is generally concieved that water mulecules do once they reach 100 degrees celcius, and boiling starts)?
This is because energy in the mass of water as a whole, is not distributed evenly between the molecules.
As a consequence, some water will vaporize, even though most of the water still is far from doing so.
So to answer the rest of the question: as the water gradually rises in temperature, more and more water will have the nessecairy energy to vaporize.
And so, at some point, the vapor pressure of the liquid, is equal to the pressure exerted on it by the surrounding environmental pressure, and at that point, the water starts boiling.

What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
When testing for differences between two means the sample population are?
You are testing the difference between two means of independent sample and the population variance are not known. from those population you take two samples of two different size n1and n2. what degrees of freedom is appropriate to consider in this case
What happens to the crtitical value for a chi square test if the size of the sample is increased?
The size of the sample should not affect the critical value.
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
What happens to a sample water when it is heated between 4c and 100c?
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
What happens to the size of a particle in a sample when liquid is heated in a closed container until it change to Gas?
evaporate
When a sample of gas is heated what happens to the motion of the particles?
When a gas sample is heated, the particles move faster and collide more frequently with each other and the walls of the container. This increased movement and collisions lead to an increase in the pressure and volume of the gas.
If a sample is heated and rises in temperature by 12 degree celsius what is this temperature difference in kelvin?
The temperature difference in Kelvin is the same as in Celsius. So, if the sample rises by 12 degrees Celsius, it also rises by 12 Kelvin.
The color of light given off when a sample is heated corresponds to?
The color of light given off when a sample is heated corresponds to the energy levels of the electrons in the atoms of the sample. Each element emits light at specific wavelengths, creating a unique spectral signature that can be used to identify elements. This phenomenon is known as atomic emission spectroscopy.
What happens if acetic acid boils at 90 degrees instead of 118?
It is most likely not acetic acid, or the sample maybe contaminated
What happens to the density of a gas sample collected in a balloon as the sample is heated?
As the gas sample in the balloon is heated, the gas molecules gain more kinetic energy and move faster, causing them to spread out and occupy a larger volume. This results in a decrease in density since the same amount of gas now occupies a larger space.
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
How fast do you heat the sample when determining a melting point?
The rate of heating when determining a melting point typically ranges from 1-10 degrees Celsius per minute, with a common standard being 2 degrees Celsius per minute. This rate ensures that the sample is heated uniformly and allows for accurate observation of the melting point.
What happens to the sample mean as the sample size increases?
With a good sample, the sample mean gets closer to the population mean.
The sample in the evaporting dish is not heated to dryness how will this affect the reported valye for total solids?
If the sample is not heated to dryness, the reported value for total solids will be lower than the actual value. This is because the remaining moisture in the sample will contribute to the weight measured, erroneously inflating the value for total solids.
