The Equation Having 5 as a Solution is:. The 4th chapter of the class 7 maths textbook is all about simple equations. This is a chapter that can be considered as really important since it helps the students in gaining Byjus Maths Class 8 Chapter 9 With some important information about equations and much more. By solving the simple equations class 7 important questions, students can learn about equations and how can one solve them using a series of formulas and shortcuts.

Also, they will be able to learn more about the different types of equations that are important for the syllabus in the best way. Expansion may apply pressure to break it. The mixture will have temperature in between 30 degree Celsius and 50 degree Celsius. They want to come on the same temperature. As one is released his temperature and other one is absorbed the temperature which is released.

Therefore, we can say heat absorbed is equal to heat released. As heat is never been destroyed. Since, the hot water at 50 degree Celsius will try to lose its heat to the cold water at 30 degree Celsius. Thermos flask is a special type of vessel which keeps hot liquids hot and cold liquids cold.

It is made in such a way as to reduce the loss of heat by conduction, convection and radiation to minimum. It is a double walled glass vessel. The space between the two walls has no air in it. It is a vacuum indeed. The inside of the outer wall and outside of the inner wall are brightly polished with silver. The whole system is enclosed in a metal case. It is supported on corks or rubber pieces on all sides. The mouth too is closed with a cork.

The vacuum between the walls prevents the flow of heat of conduction and convection. As for radiation, the brightly polished outer surface of the inner wall is a slow radiator of heat. The little heat that radiates is reflected back by the inner brighter surface of the outer wall. So, the hot liquid remains hot for a long time in the flask. Temperature is generally measured in Celsius or Fahrenheit scale.

Kelvin scale is used for scientific work. It covers the entire chapter 4 of grade 7 Science including all important terms. Q1 Boojho wonders why the level of mercury should change at all when the bulb of the thermometer is brought in contact with another object. Because mercury is a Byjus Class 10 Maths Chapter 3 Zip liquid material. Because bulb have no kink.

Temperature of object may not same as mercury. Every object has different temperature. Explanation: The temperature of another object may not be the same as that of the bulb of the thermometer.

Q2 Cooking utensils are made of metals because they are. Good conductors of heat. Do not break on heating. Explanation: We know that metals are good conductors of heat and electricity. Q3 Which of the following is a poor conductor of heat? Explanation: As we know, that gold and silver are the best conductor of heat and electricity whereas tungsten is a poor conductor of heat and electricity.
