What do understand by glass transition temperature. Explain whether it is exothermic or endothermic?
Archit111
glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.

What H2O(l) plus heat H2O(g) exthermic or endothermic?
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.

What are the uses and advantages of centigrade?
Centigrade is the scale of measuring temperature of a body or anything. By knowing the temperature, We can understand and explain several physical chemical and biological phenomena
Why is there a lower limit to temperature but not an upper limit?
lower limit because the particles have zero energy. there is no upper limit because particles can move as fast as they like. There is an upper limit on temperature, called "Planck Temperature". It is approximately 1.42e32 Kelvin! This temperature is the maximum temperature something can attain, with the physics we understand.
When a cold temperature is added to a liquid it turns to gas?
First you can not add a cold temperature to anything. Ask your teacher to explain what heat is an what temperature is, because you clearly do not understand this. When a liquid BOILS - it turns into gas. When a liquid FREEZES - it turn into a solid.
Which group of vertebrates temperature is stable?
I don't fully understand the question, but from what I gather the two types are birds and mammals. Sorry if this isn't correct. Endothermic means self-regulating body heat by the way.

What is transitions in writing?
Transition just means moving. In writing, transition is "taking the reader along" when you move from one idea to the next. It means making sure they understand and keep reading. Ways to transition can be very simple - using phrases like "for example," "next," or "in conclusion" - or it can be more complicated - following a specific type of organizational pattern. The only reason you need transition is to make sure your reader understands you - if you read your work out loud or let someone else read it, and they can follow along and understand, then you are using transition correctly. If someone says use transition words those are words that are like first, next, therefore words that go in the front of a sentence also.
What is the body temperature of a thermometer?
I don't understand your question. Thermometers are inanimate objects and thus have no body temperature
What are the 3 options of transition effects on power point?
There are many more than 3 options of transitions in PowerPoint. Perhaps I don't understand your question.
What is a transistion curve?
There are many different types of transition curves but...'Transition Curve', a simple tool used to understand the sorts of issues people might be facing during changeA track transition curve, transition spiral, or spiral easement, is a mathematically calculated Euler spiral fitted between a straight (also known as tangent) and a circular curve on a section of rail track or highway.Website-- http://en.wikipedia.org/wiki/Track_transition_curve--Sillypinkjade------

What subject would you be studying if you want to understand temperature?
A glass of water and a tray of ice.
Is temperature of water rising an example of kinetic energy?
Yes,if you understand that what makes the water temperature rise is an increase in the particle motion ( internal kinetic energy).

What development marked the transition from prehistory to the historical age?
The development of writing is typically seen as the transition from prehistory to the historical age. Writing enabled the recording of events, ideas, and advancements, allowing for the preservation and transmission of knowledge across generations. It also marked the beginning of the written records that historians rely upon to study and understand human history.
