The sample of metal is heated to 100°C before it is added to the calorimeter. The calorimeter is allowed to sit for five minutes, and the temperature is monitored until the overall system (both water and metal) reaches thermal equilibrium at a temperature of 15.5°C. You are given an 80-gram sample of metal and a small calorimeter determine the specific heat of the sample. Before adding the sample, 150 grams of water are added to the calorimeter, and the starting temperature of the water is measured to be 14.1°C. You know that the specific heat of water is approximately 4.184 J/g C. Calculate the heat absorbed by the water after the metal is added to the calorimeter.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on
