Sand needs least energy to increase the temperature as its specific heat is very low compared to that of water. Water needs more energy to increase its temperature as its specific heat capacity is higher.

Explain why vapor pressure increases as temperature increases?
Vapor pressure increases as temperatures increase because water will evaporate in hot weather. This evaporation rises increasing the vapor pressure. This is why many areas have high humidity in the summer.
How the kinetic energy of a truck could be increased without increasing the truck's speed explain?
Increase mass For a truck increase the load on the truck
Does two objects at different temperature have same thermal energy explain?
No,two objects at different temperature does not have the same thermal energy because both objects have different temperature .object with high temperature has more thermal energy and the object with low temperature has less thermal energy.
How heat energy is produced by friction?
In physics, why is always harder to explain than what. To this day, we do not know why gravity attracts mass and space, we just know that it does. Nor do we know why there is quantum jitter at the subatomic level, we just know that there is. In fact, heat is not generated by sliding friction. Temperature is raised by sliding friction, but temperature is a measure of the average kinetic energies of the atoms and molecules of the material whose temperature we take. In fact what happens is the kinetic energy and work of the mass sliding over the surface against a friction force is transfered in some part to the atoms and molecules of the matter of the surface. That energy transfer in turn raises the average kinetic energy of the atoms and/or molecules. And we measure that increase as an increase in temperature..typically in degrees Kelvin. It's particle kinetic energy and temperature, not heat, that increases with sliding friction action. But, over time, we've come to call the atomic/molecular kinteic energy heat to show this specific kind of KE can be measured as temperature. In fact, what we call heat can be best described as a change of heat over time dq/dt ~ del(T); where delT is a temperature difference in degrees K, across some medium through which the heat is changed. How much heat is changed over time also depends on the physical characteristics of the medium; like the specific heat coefficient, the area and thickness, etc.
Make a hypothesis state which of three insulating materials you think will keep the inside temperature of the house higher than outside temperature for the longest period of time an explain why?
thermal energy molecule
Can you explain the gases in the pressure cooker?
By heating the pressure increase and again the temperature increase.
Explain how a global temperature increase could affect plants?
A small increase in temperature may help some plants, but will be damaging to others. A large increase in temperature will kill most plants.
How do you explain the increase in pressure in a closed system when temperature is increased?
Since the temperature is increased, the molecules start moving to and fro... which tends increase in speed of the molecule.. such that the increase in temperature is directly proportional to the speed of the molecules by which the pressure will also increase...
Is it possible to attain a temperature less than zero degree kelvin explain?
No.To explain requires many years of education
Explain why increasing the temperature of a gas in a close the rigid container causes the pressure in the container to increase?
If temperature increases, either the volume or the pressure must increase. Since you have limited the volume by closing the container, pressure must increase.
Explain why increasing the temperature of a gas in closed rigid container causes the pressure in the container to increase?
Because the pressure increases The real answer is: Charles's Law. He found that if you increase the temperature of a constant pressure the volume increases also.
Does the movement of woodpecker involve friction force explain?
Every movement you make requires friction. When you walk, it requires friction. When a woodpecker is pecking a hole in a tree, it requires friction for him to keep his toes in the tree- static friction, to be specific. Hope that helped!
Explain meaning of annual range of temperature?
explain the temperature annual range
Explain why the temperature of the atmosphere does not increase or decrease steadily as you move from earth's surface toward space.?
The distribution of temperature in the stationary heated solar atmosphere found for the limiting cases of slow and fast heating.
Explain the change in rate of photosynthesis as the water temperature increased from 18 degrees to 31 degrees?
Rate of photosynthesis decreases because the tissues which helps in transport of water stop transporting due to increase in temperature and hence change in rate of photosynthesis decreases.
Explain why judging the efficiency of any financial decision requires the existence of a goal?

What is machinery?
shaving down the heads on an automobile is the easiest way to explain it but anything that requires very specific and delicate cuts. It is definatly an art and machinest useally doesnt get enough credit.
