Is Temperature a measure of the amount of heat stored in a substance?
No. As Temperature isn't by any way a measure of how much energy is ''stored'' in a substance, it vary with the heat capacity of the said substance...«Heat capacity (usually denoted by a capital C, often with subscripts), or thermal capacity, is the measurable physical quantity that characterizes the amount of heat required to change a substance's temperature by a given amount. In the International System of Units (SI), heat capacity is expressed in units of joule(s) (J) per kelvin (K).»
What is the measure of the amount of heat an object has?
Heat capacity is generally measured as Jule per Kelvin in SI system. It is the the amount of heat required to change a substance's temperature by a given amount.
Dimensional formula for heat capacity and specific heat capacity?
heat capacity- ML2T-2K-1 Specific Heat Capacity-M0L2T-2K-1
What is relation between heat capacity and specific heat capacity?
The "specific heat capacity" is simply the heat capacity per unit - it might be per mass unit, per volume unit, or per amount of moles.
Does a thermometer bulb have large heat capacity or small heat capacity?
A thermometer bulb should have.small heat capacity. In case if it has large capacity, the temperature of the substance will get lowered due to the large amount of heat absorbed by the thermometer bulb
What is a thermometer used to measure?
Temperature measures relative energy of an object. It does not measure heat. The amount of heat (energy) depends on the size of the object, the nature of the material / its heat capacity.

What is thermal capacity?
The physical quantity which is used to measure the amount of heat needed to raise the temperature of a given substance is known as heat capacity or thermal capacity. Its S.I. unit is J/K.
What is specific heat capacity and what does it measure?
Specific heat capacity(q) is the amount of heat needed to raise a tamperature of a body with mass of 1kg by 1K or 1 decree celcius. The formuale to calculate it is c(specific heat capacity) = Q/mass x change in temperature.

How do you measure molar heat capacity?
Specific heat is the heat capacity divided by the heat capacity of water, which makes it dimensionless. To obtain molar heat capacity from specific heat for a material of interest, simply multiply the specific heat by the heat capacity of water per gram [1 cal/(g*C)]and multiply by the molecular weight of the substance of interest. For example, to obtain the molar heat capacity of iron Specific heat of iron = 0.15 (note there are no units) Molar heat capacity of iron = 0.15*1 cal/(g*C)*55.85 g /gmole = 8.378 cal/(gmole*C)
What is the measure of the amount of heat an object has?
Heat capacity is generally measured as Jule per Kelvin in SI system. It is the the amount of heat required to change a substance's temperature by a given amount.
If the heat capacity of an object is known what other information will need to be known to calculate its specific heat capacity?
By using the definition of "specific heat". You add a certain amount of heat, and see how much the temperature increases. You also need to measure the sample's mass. Then divide the amount of heat by (mass x temperature increase).
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
Why would a plastic kettle stay hotter than a metel kettle?
How long something stays hot depends on its heat capacity. Heat capacity is a measure of the amount of energy required to change the temperature of an object.Water has a relatively large heat capacity per gram whereas metals have a low heat capacity. This means that water retains it heat but metals heat and cool quickly. We can take a metal tray from an oven and put it to cool, we can touch the tray soon afterwards but the roast that we put on the serving platter stays hot for a lot longer.The plastic in the kettle will cool depending on its heat capacity. Metal cools quickly due to its low heat capacity.
Is it possible to measure heat using a thermometer?
yah sure but u need some parameters like specific heat capacity and its mass and by the relation Q=mcdt,we can the heat content of that body
