*Please help me for 55 points and please be detailed (to branliest): 1. How many calories are needed to raise the temperature of 1 gram of water by 10 degrees celsius?

2. Two vehicles are traveling at the same speed (one is a car and one is a big rig). What do you know about the kinetic energy of the vehicles?

3. As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting?

4. Which of the following terms means the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celcius?

5. An ice cube sits in an open container of water outside in the hot sun. The warmer water contacting the ice cube transfers energy to the ice cube through what process? Compare the speeds of the particles of the ice, water and water vapor.

#1We want to raise the temperature of a mass m of 5g of water through 10C degrees.

The heat capacity of water Cp is nominally 4.186J/g-C or 1.0cal/g-C,

So the heat required is ΔH = m•Cp•ΔT = 5 x 1 x 10 = 50cal

#2  a. the linear momentum of both vehicles is equal.

#3 The transfer of thermal energy to the ice cube causes it to become liquid water. ... The loss of thermal from the water causes its molecules to move slower

#5

Adding heat would cause melting of an ice to a point where it becomes a water. But, if adding of heat is continued, water can slowly evaporates which can result in decreasing of water volume and forming of aerated water.

If we compare speed of particles of ice, water and air we can notice big difference. Ice is a solid substance that is very cold. These two combined characteristics bring very slow motion of particles with low vibration rate. Water is liquid. Liquids have faster moving of particles in comparison with solids. They tend to slide against each other while moving. The fastest movement have gases. Their particles have enough space between each other to move freely and vibrate a lot.
