What is the temperature change of an 36-gram sample of water that had absorbed 695 Joules of heat? C = 4.18 J/g K
maks197457 [2]

The temperature change of a 36-gram sample of water is <u>4.61 K</u>

Temperature is the degree of the average kinetic energy of the debris in an item. while the temperature will increase, the movement of this debris additionally will increase. Temperature is measured with a thermometer or a calorimeter.

heat = msΔt

     695 Joule = 36 ×  4.186 × Δt

Δt   =  695/ 36 ×  4.186

      = <u>4.61 K</u>

Temperature is just a dimension that indicates the common kinetic energy of 1 atom or molecule. as a result, when we are saying something is warm or bloodless, we're generally using any other reference point to define the hotness and coldness of a frame.

Two different samples of solid iron are shiny, can be made into wire, and can rust when exposed to water. Why do the two samples
Montano1993 [528]

Answer:

The two samples have identical properties because they are the samples of the same element. Intensive properties are properties of matter that do not change depending on the amount of matter. Luster, reactivity, and ductility are all intensive properties. That is why the two samples can be different sizes or shapes, but have identical properties.

PLEASE HELP!!! URGENT!!! WILL GIVE BRAINLIEST
Kisachek [45]

Answer:

A silicone atom shares an electron pair with each oxygen atom

Explanation:

Because the silicone dioxide molecule has one silicone atom:two oxygen atoms....

Hence...since silicone has four electrons in the outter shell..which are used for bonding...each oxygen atom shares two electrons(an electron pair) with the silicone atom...so as to fill the outter shell of the oxygen atom

Refrigerators are usually kept at about 5°C, while room temperature is about 20°C. if you were to take an empty sealed 2 liter s
MakcuM [25]

Answer:

c) No, because Celsius is not an absolute temperature scale

Explanation:

converting  5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K

and converting 20 oC to kelvin = 20 + 273 = 293 K

the ratio = 278 / 293 = 0.94 approx 1 not 4
