pascal is the unit of pressure
The units of pressure is called derived units because it is simply derived from base unit which is distance and a derived unit which is force, which is derived from acceleration, a derived unit as well, and mass, a base unit. As we all know, work is defined as the force x distance. Thus making work a derived unit.Jun 23, 2020
Answer:
-47 J
Explanation:
Given that,
Heat loss = -76 J (negative for loss)
Work done by the surroundings = -29 J
We need to find the change in internal energy of a system.
The first law of thermodynamics is given by :
W is work done by the system
Putting all the values,
Hence, the change in internal energy is -47 J.
The main difference between series and parallel circuits is that, in series circuits, all components are connected in series so that they all share the same current whereas. In parallel circuits, components are connected in parallel so that they all have the same potential difference between them
Answer:
Nothing goes to Kinetic Energy
Both-1, 2, 4
Potential Energy-3 and 5
Explanation:
Chemical properties include corrosive, change in concentration of hydroxide ions when added to water, and forms hydrogen gas when in contact with a metal.
Physical properties of matter are those properties that are determined using senses or instruments. Hence, odor, taste, and texture are physical properties.
The chemical properties of a substance describe how the substance is converted to another substance.
Corrosion is the property of a substance that creates rust under the influence of oxygen from the air.
Some metals in contact with water produce hydroxides where hydrogen is also formed.
A concentration of hydroxide ions in the solution decreases due to dilution when water is added.
