DNA duplex strands are bonded by hydrogen bonds. On heating the hydrogen bonds break. At specific temperature called Tm half of the double helix is broken down (separated from each other) while the other half remains as such. This temperature can be determined , also the GC bond is stronger than AT so in such cases the temperature is more if the helix has more GC bonds.

Limitations on aluminium sheet imposed by over heating?
It melts
What happens to sulfur when you heat it in a test tube?
It melts. This is assuming you're heating it in the absence of oxygen, or at least in such a way that it doesn't burn.
Does a wet rock generally melts at a lower temperature than a dry rock true or false?
True, a wet rock melts at a lower temperature!
What temperature melts a solid?
The temperature at which intermolecular forces push the molecules apart
When a substance melts the temperature of the substance?
it decreases.
How Can Solid melts without heating?
i think through temperature which is present in our environment.
What is the nature of a solid when it is heated it melts at a definite temperature and further heating produces black solid and a gas?
carbon
Why is the salol a crystalline solid?
It's made up of crystalls and it melts at its specific temperature.
What problems do you see with a material like nylon that melts on heating?
metal melts on heating because it gets hot
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
How does liquids turn into a solids?
To turn from a solid to a liquid it must reach it's melting point by heating up. Examples: ice to water, rocks to magma. Every thing melts at a different temperature.
How does heating a solid turn into a liquid?
it melts
Why a DNA duplex melts at a specific temperature (Tm) on heating?
At a certain temperature (around 50oC) the hydrogen bonds between nitrogenous bases on each strand of the double helix (or DNA duplex) become unstable and broke apart and therefore both strands tend to separate. On the other hand, the stability of the DNA double helix, and hence its Tm, depends on several factors, including the nature of the solvents, the identities and concentrations of the ions in solutions, and the pH. Tm also increases linearly with the mole fraction of G-C base pairs, which indicates that triple hydrogen-bonded G-C base pairs are more stable than doubly hydrogen-bonded A-T base pairs.
What is caramelise?
Caramelise is heating sugar until it melts.
Do energy melts ice?
Yes, ice is melted by heating.
Limitations on aluminium sheet imposed by over heating?
It melts
How the energy of matter changes when it melts.?
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
