Answer: The specific heat of the liquid is 
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of glass = x kg
= mass of liquid = x kg
= final temperature =
= temperature of glass = 
= temperature of liquid = 
= specific heat of glass = 
= specific heat of liquid= ?
Now put all the given values in equation (1), we get
![-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)](https://tex.z-dn.net/?f=-%5B%28x%5Ctimes%20840%5Ctimes%20%2853-83%29%5D%3Dx%5Ctimes%20c_2%5Ctimes%20%2853-43%29)
Therefore, the specific heat of the liquid is
Answer: The answer is A.
Explanation: The higher the kPa, the lower the boiling point
Answer:
Iron and vermiculite.
Explanation:
Iron and vermiculite are the solid substances used to make a hand warmer. Hand warmers contains iron, water, activated carbon, vermiculite, cellulose, and salt. The high melting, boiling points, hard and brittle are the characteristics of an ionic solid used in hand warmer. Iron is the ionic solid which is used in the hand warmer. Once iron exposed to air, the iron oxidizes and releases heat in the process.
The right answer is the last one hope this helps your very welcome
The scientists produced an adhesive that was made from carbon nano tubes. The adhesive has two different layers; the lower layer is composed of vertically aligned nano tubes while the upper layer is made up of curly nano tubes that are spaghetti - like in shape.
The adhesive device produced can hold a maximum force of 700 pounds while adhering to a smooth surface.<span />
