Answer: a. 1,000 g of water

Explanation:

Heat capacity is defined as the amount of heat required to raise the temperature of a substance through 1 degree Celsius.

$Q= m\times c\times \Delta T$

Q= heat gained

m= mass of the substance

c = heat capacity

Heat capacity of water = $4.186 J/gram^0C$

Heat capacity of steel = $0.49 J/gram^0C$

Hence 1,000 g of water will have greatest heat capacity.

If an atom has 35 protons in the nucleus, how many will it have orbiting nucleus

yan [13]

It will have 35 ''electrons'' . Basically the number of protons in the nucleus of an atom is always equal to the number of electrons but its just that protons are positively charged and electrons are negatively charged. <span />

How much energy, in joules, does 150.0 g of water with an initial temperature of 25 C need to absorb be raised to a final temper

satela [25.4K]

Answer:

31395 J

Explanation:

Given data:

mass of water = 150 g

Initial temperature = 25 °C

Final temperature = 75 °C

Energy absorbed = ?

Solution:

Formula:

q = m . c . ΔT

we know that specific heat of water is 4.186 J/g.°C

ΔT = final temperature - initial temperature

ΔT = 75 °C - 25 °C

ΔT = 50 °C

now we will put the values in formula

q = m . c . ΔT

q = 150 g × 4.186 J/g.°C × 50 °C

q = 31395 J

so, 150 g of water need to absorb 31395 J of energy to raise the temperature from 25°C to 75 °C .

An object has a mass of 4 grams and a volume of 2 cm^3.what is the density of the object?

stellarik [79]

Answer:

2.0 grams per cubic centimeter

Explanation:

(You can refer to the DMV triangle to help you solve this!)

Density = Mass/Volume

Density = 4.0g/2.0cm3

Density = 2.0g/cm3

Hope this helps!!!
