Q3. What is tha water cement ratio
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio affects the strength and durability of concrete.

• Lower water cement ratio results in stronger concrete but may be difficult to work with.

• Typical water cement ratio ranges from 0.4 to 0.6 for normal strength concrete.

• Excess water can lead to lower strength and durability of concrete.

Q6. Heat transfer and types
Ans. 
Heat transfer is the movement of heat from one object to another due to a temperature difference.
• There are three main types of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself.

• An example of conduction is when a metal spoon in a hot cup of tea becomes hot.

• Convection is the transfer of heat through the movement of fluids...read more
