cbse class 11 physics thermodynamics important question and sample paper

2. a) Liquid nitrogen boiling at -196°C is a physical property because it describes the boiling point of a substance, which is also when it changes state. A change of state, from a liquid to a gas, is a physical property because there is no new substance being created.

Everything possible is done to ensure that people have symptoms under control and are as well as they can be. The model recognises the need for people to receive care and to have their needs met. This can be at home, or more often in a residential or nursing home. Families and carers are supported to look after the person with dementia and are kept informed on all aspects of a person’s care. Plans are developed in consultation with carers: risks to the person are considered and steps put in place to ensure that people are kept safe.

the properties of the system as a whole can be encompassed by considering the individual systems, e.g.,

There are 2 things we've recently done that may be confusing to what we're trying to accomplish.

the system will, on a large scale, form a network of independent components which ultimately

It is very important to try hard to reduce your chances of getting an illness or getting injured. For example, when you go snowboarding during the winter, it is very important that you wear enough clothing to stay warm and don’t get cold. Also, it is important that you wear protective gear to keep you safe. Also, if you have a certain disease, it is important that you take care of it. Like for people with asthma, they have to make sure they take their medication so that they can reduce the risk of them having an attack. Another thing you can do is make sure you get vaccinated for diseases. I hope that through this issue, you can learn the different ways to reduce your chances of getting an illness or infection.

The Stages of Deception used as a way of Persuasion and the thought of Hope

The first is named $S_{6,L_3}$ or $\ll$\textit{break}$\gg$. In order to be in this state, $C_{6,L_2}$ has to be fulfilled and this condition requires a constant $z$-position and constant forces and torques. It is defined by the domain expert that a constant $z$-position and changing forces and torques are equal to the condition $C_{5,L_2}$. The corresponding state is named $S_{5,L_3}$ or $\ll$\textit{blocking}$\gg$. This is a very interesting state because it contains a problem during task execution. On higher decomposition levels, the substates of this state also describe how the problem was handled in order to solve it. But on higher levels, the domain expert has to be aware of the maximal human movement frequency in order to identify intended human actions. If a state does not take enough time, it can represent an intended movement. So the domain expert has to define a $C_R$ according to the maximal movement frequency of a

This question concerns the main security goals (confidentiality, integrity, availability). Describe a situation in which the goal of integrity is important, but there is not a need for confidentiality.

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

S. Eddington awarded the second law of thermodynamics "the supreme position among the laws of Nature" since it alone was responsible for what he was the first to call "time's arrow"… The directionality of time that results from entropy's increase, Eddington points out, is intimately installed in our awareness of ourselves in the world, confirmed by human reason, and dependent upon the fact that there are multiple parts to be organized or disordered (Menke, 970).

4. Give three examples of subsystems not operating in the context of IT. Why are these considered subsystems and not systems?

can be seen that in the real world the system is composed of of various types of

Since we are interested in faults and degradation, the system will have three modes and one continuous state, i.e.:
