Answer:
Explanation:
-Specific heat capacity is given by the formula:
Where:
is the heat gained or loosed by the substance
is the mass of the substance
is the specific heat of the substance
is the change in temperature
#We make c the subject of the formula and substitute to solve for it:
Hence, the specific heat capacity of the ice is 
Answer:
A.A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. ... These collisions of the gas particles with the container walls exert pressure on the walls of the container.
B A gas exerts pressure on the walls of the container due to imapact of its gas molecules with hight velocity .
C.A wooden table should be called a solid. Reason: It has a definite shape and volume. It is very rigid and cannot be compressed, i.e., it has a solid characteristic.
D.We can easily move our hand in air but to do the same through a solid block of wood we need a karate expert. It is because the molecules of air has less force of attraction between them and a very small external force can separate them and pass through it.

Answer:
Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.
Explanation:
The answer would be 560,848,164 because the 0 at the start WOULDNT matter
