Which of the following describes the amount of heat needed to raise the temperature of
one gram of a substance by one degree?
11°

Specific heat.

Specific heat

Explanation:

The specific heat of a substance is the amount of heat required to raise the temperature of 1g of such substance by 1K.

  Specific heat of substance depends on the nature of the substance. For most conductors of heat, specific heat value is quite low because increase in temperature is attained very fast.

But for poor conductors such as water, they have a high specific heat capacity. They do not lose nor gain heat readily. More heat must be supplied to cause a significant rise in temperature.

  The relationship;

         H  = m x c x Ф  

 shows the relationship between the amount of heat, mass , specific heat and temperature change.

         H is the amount of heat

         m is the mass

          c is the specific heat

          Ф is the temperature change

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
