This mug is made of two layers of glass separated by empty space. it is more effective than a ceramic mug at keeping the beverage warm. why is this design more effective?
a. the beverage has a higher temperature than the air.
b. the air is warmer than the mug.
c. the particles that make up the glass have no thermal energy.
(answer) d. the empty space has no particles to transfer thermal energy.

D. The empty space has no particles to transfer thermal energy.

Explanation: Thermal energy is the energy possessed by an object by virtue of its temperature.

There are three modes of transfer of thermal energy

1.Conduction: This type of heat transfer happens when there is direct contact between the two objects.

2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

As there is empty space between the two layers of glass , the thermal energy cannot be transferred by conduction and thus the beverage remains warm.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

the components of a vector are the parts of the vectors that are to each other.
