Answer: The object will move in the South direction.
Explanation: We are given an object of 400 N and force acting on it is 420 N from the north direction, it means the force is acting towards south.
The object will move in the direction of the net force, which is south direction.
Hence, the correct option is A.
I believe a hydrochloric gas will be let off
Answer:
The answer to your question is C = 0.037 cal/g°C
Explanation:
Data
mass of the wire = m = 237 g
temperature 1 = T1 = 25°C
temperature 2 = T2 = 107°C
Heat = Q = 722 cal
Specific heat = C
Process
1.- Write the formula to find the specific heat
Q = mC(T2 - T1)
-Solve for C
C = Q / m(T2 - T1)
2.- Substitution
C = 722 / 237(107 - 25)
3.- Simplification
C = 722 / 237(82)
C = 722 / 19434
4.- Result
C = 0.037 cal/g°C
Vapor pressure of a liquid increases with increasing temperature because increasing the temperature results in increasing kinetic energy and increase in molecular transition and motion.
What is Vapor Pressure?
- The pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a specific temperature in a closed system is referred to as vapor pressure.
- A liquid's evaporation rate can be determined by looking at the equilibrium vapor pressure. It has to do with how often particles tend to float away from liquids (or a solid).
- Volatile is a term used to describe a chemical that has a high vapor pressure at room temperature. Vapor pressure is the force that vapor exerts when it is present above a liquid surface.
- A liquid's molecules have an increasing kinetic energy as its temperature rises. The more molecules that convert into a vapor as a result of an increase in molecular kinetic energy, the higher the vapor pressure will be.
