Answer:

1. reduce green house emissions

2. remove carbon from atmosphere

3. governmental policies

Explanation:

1. the green house gases form like a blanket absorbing radiation and not not letting it escape, gradually heating up the earths surface. so a reduction on energy use is needed.

2. this can be done by planting more trees or plants in general

3. governmental policies are needed to regulate green house gases and limit them.

Protactinium has 516 years of half life how many decays will it go through to become 1/64th of the substance? ,

Ulleksa [173]

Answer:

6 decays

Explanation:

Each half life period reduced the amount of substance by half

64 = 2⁶
1/64 = (1/2)⁶

So 6 of half life cycles or decays will go.

Specific Heat Material Copper Aluminum Gold Pyrex Specific Heat (J/g °C) 0.385 0.902 0.129 0.75 Material Water Ice Olive Oil Air

zimovet [89]

Explanation:

It is known that the amount of heat necessary to raise the temperature of 1 gram of a substance by $1^{o}C$ is known as specific heat.

Since, q = $mC \Delta T$

So, larger is the specific heat of a substance less will be the change in its temperature.

Therefore, olive oil has less specific heat as compared to water. This means that olive oil would get hotter.

Similarly, the specific heat of gold is lesser than the given materials or metals. Hence, gold will requires less heat to rise its temperature.

As a result, water present in gold will heat readily.

As the relation between heat and specific heat is as follows.

q = $mC \Delta T$

Therefore, calculate the amount of heat required by the water as follows.

q = $mC \Delta T$

= $100 g \times 4.18 J/g^{o}C \times (100 - 20)^{o}C$

= 33440 J

or, = 33.44 kJ (as 1 kJ = 1000 J)

Thus, 33.44 kJ heat would it take to raise the temperature of 100.0 g of water from $20.0^{o}C$ to $100.0^{o}C$ .
